CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract—Gestational Diabetes Mellitus (GDM) is a problem which may occur during pregnancy. For
treatment of GDM either the Metformin or Insulin is used. So this prospective randomized multicenter
trial in women with GDM was conducted to compare the treatment outcomes of metformin and insulin.
This study was conducted at Rajkiya Mahila Chikitsalaya, in Obstetrics & Gynaecology Department of
Jawaharlal Nehru Medical College, Ajmer. This study was done on 110 women who were diagnosed
GDM by DIPSI criteria with a singleton pregnancy and meet entry criteria are randomized to insulin or
metformin treatment (55 cases in each group).It was observed that metformin is equally efficacious and
safe as insulin with a lot of advantages like less costly, better compliance, less weight gain, less change
of hypoglycaemic attack and more feasible as insulin require several daily injection with not much
difference in perinatal outcome except statistically significant difference in baby weight, mean cord
blood sugar level at birth, large for gestation age. So it can be concluded that Metformin treatment is
suitable for non-obese as well as obese type 2 diabetes patients in pregnancy without complications.
Metformin is a safer alternate to insulin in GDM management with no adverse maternal and fetal
outcome.
Keywords: Gestational Diabetes Mellitus (GDM), pregnancy outcomes.
I. INTRODUCTION
Gestational Diabetes Mellitus (GDM) is defined as any degree disturbance of glucose metabolism with
onset or first recognition during pregnancy.1,2 The prevalence of GDM varies worldwide from 1 to 25%
according to the ethnic population and the criteria used in the diagnosis.3 Screening policies regarding
GDM and the diagnostic criteria vary according to the different recommendations.4
The initial recommendation for using 75-g Oral Glucose Tolerance Test (OGTT) in pregnancy was from
the World Health Organization (WHO). The WHO used the same criteria for diagnosing diabetes both
during and outside of pregnancy.5 This approach was criticized, as it ignored the physiological changes
in carbohydrate metabolism that occurs during pregnancy. In 1999, the WHO lowered the threshold for
FPG from 7.8 mmol/L (140 mg/dL) to 7.0 mmol/L (126 mg/dL) and recommended that pregnant
women meeting the criteria for diabetes mellitus or impaired glucose tolerance (IGT) be classified as
having GDM5. The current 75-g International Association of the Diabetes and Pregnancy Study Groups
criteria (IADPSG) criteria have been devised keeping this fact in mind and evaluating evidence that
associates abnormal glucose tolerance in pregnancy with adverse perinatal outcomes.6
Unblinded studies since 1995 have shown adverse perinatal outcomes to be linearly linked with
glycemic levels in gestation7. The landmark study in this respect was the Hyperglycemia and Adverse
Pregnancy Outcome (HAPO) study8. The HAPO study was a large, multicenter, multinational,
epidemiologic study in which 23,316 women (30 times larger than the O’Sullivan cohort) underwent

blinded 2-hour, three-sample, 75-g OGTTs at 24–32 weeks of gestation. All women with a fasting
plasma glucose (FPG) 5.8 mmol/L (105 mg/dL) and 2 hours values up to 11.1 mmol/L (200 mg/dL)
were included.7,8
GDM is associated with an increased risk of a variety of maternal and perinatal complications, including
preeclampsia, caesarean section, macrosomia, shoulder dystocia, instrumental delivery, birth injuries,
hypoglycemia and respiratory distress syndrome (RDS), Neural Tube Defect (NTD), cardiac anomaly
like VSD, ASD , still birth , neonatal death resulting from excess transfer of glucose from mother to
fetus.8,10
The treatment of GDM improves pregnancy outcomes by reducing the incidence of macrosomia, pre-
eclampsia and hypertensive disorders.11 Diet therapy and self-monitoring of blood glucose
concentrations are key factors in the treatment of GDM.12,13 Traditionally, Insulin therapy has been the
first line medical treatment in GDM, but recently oral hypoglycemic agents, especially Metformin and
Glyburide have been under investigation. Women with GDM are known to carry an almost eight-fold
risk of subsequent Diabetes Mellitus later in life. In addition, GDM has been found to be associated with
a later risk of Metabolic Syndrome (MetS) and cardiovascular diseases. The offspring of women with
GDM have an increased risk of later Obesity, Diabetes and Metabolic Syndrom (MetS).14,15
So this comparative randomized trial was conducted to compare the effects of Metformin and Insulin in
treatment of GDM.
II. METHODOLOGY
This prospective comparative interventional study was conducted on 110 women with GDM at Rajkiya
Mahila Chikitsalaya, in Obstetrics & Gynaecology Department of Jawaharlal Nehru Medical College,
Ajmer (Rajasthan) India. This study was aproved from institutional ethical committee.
For this study, all single tone pregnant women, who were diagnosed GDM as per Diabetes in
Pregnancy Study Group India (DIPSI) criteria, delivered in Obstetrics & Gynecology department at
Rajkiya Mahila Chikitsalaya, Ajmer were included. Out of these women, women either previously
diagnosed DM or having previous bad obstretic history was excluded from study. Even women sensitive
to either Metformin or Insulin were also excluded from study. Those refusing to give consent to
participate in the study were also excluded from study.
HbA1C was done for all women whose blood sugar level (BSL) were 140mg/dl and referred to a
diabetologist and managed with joint care. If BSL was normal, the screening criteria was repeated
between 24 and 28 weeks of gestation and same screening criteria was applied.
Subjects have been followed through their index pregnancy and blood glucose level monitored. Blood
Glucose monitoring by a Glucometer was encouraged. Target blood sugar levels was aimed at FBS
equal or less than 100 mg/dl and 1 hour postprandial level equal or less than 140 mg/dl. Initially GDM
has been managed by diet and exercise for two weeks. If blood glucose was not controlled,
Pharmacotherapy has been instituted. These women were enrolled for the study. Finaly 110 eligible
women participated in this study.
Sample size was calculated 49 subjects for each of the two groups at alpha error 0.05 and power 80%
assuming minimum difference of means to be detected of 2HPG between the two (Metformin and

Insulin) groups, 4mg/dl with standard deviation 0. 22 mmol/l (Rowan JA et al., 200816). To estimate an
appropriate sample size the following formula was used
N (per group) = Z [
( 𝑧

+𝑧 𝑎) 𝑎
∆
]2
Where n = sample size (per group), Z𝑎/2 = (1.96) for 95% confidence (i.e a =0.05)
𝑍𝑎 = cut off value for power (1 – β), a = Common standard Deviation of both groups, ∆ = Mean
difference to be detected (From a previous study (Rowan JA et al., 20087), a minimum difference of
4mg/dl (0. 22 mmol/l) was estimated in the mean 2HPG between the two groups)
After taking written informed consent from the all eligible 110 participants, a detailed history was taken.
Height in cms and weight in kgs was recorded and BMI was calculated. A general, systemic and
obstetric examination was done.
Then these women were randomized into 2 groups. One group given tablet Metformin orally and the
other group given injection Insulin subcuteneously. In the Metformin group, the starting does of
Metformin was 500 mg once a day and increased gradually over time according to blood sugar values.
The maximum dose allowed per study protocol was 1500 mg per day. Insulin was added if targets were
not reached on Metformin alone at maximum doses. In the Insulin group, Insulin was administered
subcutaneously in the thigh or abdomen. Insulin doses were adjusted by Diabetologist as per BSL
(blood sugar level). Frequency of monitoring was being decided based on BSL. The total dose of insulin
was titrated for each patient to achieve the optimum Glycemic targets. The women were asked for
follow up monthly till 28 weeks. Then fortnightly till 36 weeks following which a weekly follow up was
recommended. More frequent visits were advised if necessary. USG was done at 7 weeks for viability,
at 12 weeks for Nuchal transparency (NT), at 18 - 20 weeks for anomalies, at 32-34 weeks growth scan
and more often if required. The frequency of visits was increased if any complication developed. After
30 weeks all pregnant women were counselled to keep a daily fetal movement count. Neonatal
hypoglycemia was defined as a blood glucose level <40 mg/dl in any infant, regardless of gestational
age and whether or not symptoms were present. Blood glucose levels were checked at 1, 2, 3, 6, 12 and
24 hours. Additional blood glucose testing was done as per Paediatric / Neonatologist recommendation.
Glucose was measured with Chemstrip BG. Reading <40mg/dl should be checked rapidly by a clinical
laboratory. The infant was fed orally or given IV glucose by 1 hour of age.
Data thus collected were compiled as master chart in MS EXCEL 2010 worksheet. Qualitative data
were expressed in percentage and proportion. Quantitative data were expressed in mean and standard
deviation. Chi-square test was used to infer the difference on proportions whereas unpaired 't' test was
used to infer difference on means of these two groups.
III. RESULTS
Metformin and Insulin group were well comparable i.e. without significant difference, as per studies
demographic characteristics like age, parity etc. Mean age was observed 30.5 ± 3.2 years and 32.3 ±
3.4 years in Metformin and Insulin group respectively, which was without significant difference
(p>0.05). Likewise, mean parity was observed 2.4 ± 1.3 and 2.9 ± 1.4 in Metformin and Insulin group

Mean randome blood sugar (RBS) and mean fasting blood sugar (FBS)of both the group was also
without any significant difference (p>0.05).
In this study among women with GDM, in Metformin group 66.67% were GDM and other were T2DM
whereas in Insulin group it was 62% and %. In Metformin group associated morbidly was Essential
Hypertension in 7.27%, Hypothyroidism 1.82% and Anemia in 1.82% whereas in Insulin group it was
5.45%, 0% and 1.82% respectively.
In this study, no significant difference was observed in maternal as well as fetal outcome in both the
groups except blood glucose level at birth of baby and large for gestational age babies were observed
significantly more in Insulin group. Other studied variables like weight gain during pregnancy,
gestational age at delivery), presence of pre-eclampcia, presence of polyhydramnios, mode of delivery,
birth weight, APGAR score of baby, IU deaths, still births and proportion of babies with various
complications were without significance difference in both (Metformin and Insulin) the groups in this
study.
Niromanesh S etall17 conducte a similar study on 80 GDM in Metforfine group and 80 in Insulin group
and observed that two groups were comparable regarding the maternal characteristics. Two groups were
similar in mean FBS (P=0.68) and postprandial measurements (P=0.87) throughout GDM treatment.
The neonates of metformin group had less rate of birth weight centile >90 than insulin group (RR: 0.5,
95% CI: 0.3-0.9, P=0.012). Maternal weight gain was reduced in the metformin group (P<0.001). Two
groups were comparable according to neonatal and obstetric complications (P>0.05). In metformin
group 14% of women needed to supplemental insulin to achieve euglycemia.
So similar to the present study, they also found that Metformin is an effective and safe alternative
treatment to insulin for women with GDM. This study does not show significant risk of maternal or
neonatal adverse outcome with the use of metformin.
Li G etall18 also concludes that Metformin is comparable with insulin in glycemic control and neonatal
outcomes. It might be more suitable for women with mild GDM. This meta-analysis also provides some
significant benefits and risks of the use of metformin in GDM and help to inform further development of
management guidelines
Liang etall19 also concluded that metformin is fastest in glucose control, with a more favorable
pregnancy outcomes-would be a better option, but its rate of glucose control is the lowest.
V. CONCLUSION
This study concludes that Metformin is an effective treatment option for women with GDM/type 2
diabetes in pregnancy with or without add-on insulin who require pharmacological treatment for
glycemic control in our resource poor setting. Metformin has advantages over insulin such as less
maternal weight gain, no maternal hypoglycemia, being less costly, being oral therapy and requiring no
vigorous monitoring and frequent hospital admissions with good compliance and acceptability. So,
Metformin can be used in the management of gestational diabetes mellitus.
