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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. WHAT IS QUALITY?
Quality means different things to different people
Following Taguchi, the quality of a product is
measured in terms of the total loss to society due to
functional variation and harmful effects. The loss
would be zero for the ideal quality.
3. TAGUCHI LOSS FUNCTION
It’s a graphical depiction of loss developed by the
Japanese business statistician Genichi Taguchi to
describe a phenomenon affecting the value of
products produced by a company.
'loss' is depicted by a quality loss function and it
follows a parabolic curve mathematically given by
L = k(y–m)2,
where m is the theoretical 'target value' or 'mean
value' and y is the actual size of the product, k is a
constant and L is the loss. This means that if the
difference between 'actual size' and 'target value' i.e.
(y–m) is large, loss would be more, irrespective of
tolerance specifications.
4. In Taguchi's view tolerance specifications are given by
engineers and not by customers; what the customer
experiences is 'loss'. This equation is true for a single
product; if 'loss' is to be calculated for multiple
products the loss function is given by
L = k[S2 + y – m)2],
where S2 is the 'variance of product size' and y is the
average product size.
7. QUALITY LOSS FUNCTION − THE

9. Average quality loss
Q = k [( m - μ )2 + σ 2 ]
It consists of two components:
Shift of process average (μ) from the target
value (m)
Spread of the process (σ2)
S/N ratios are a log-modified form of Average
quality loss function
10. TAGUCHI PHILOSOPHY
1. Quality should be designed into the product and not
inspected into it.
2. Quality is best achieved by minimizing the deviation
from a target. The product should be so designed
that it is immune to uncontrollable environmental
factors.
3. The cost of quality should be measured as a function
of deviation from the standard and the losses should
be measured system-wide.
11. Maximizing S/N ratio is equivalent to reducing variance
due to various noise factors and hence improves quality
during manufacturing, customer usage and aging and
simultaneously reducing cost substantially.
S/N ratio
12. Taguchi specified three situations:
Larger the better (for example, agricultural yield);
Smaller the better (for example, carbon dioxide emissions);
On-target, minimum-variation (for example, a mating part in
an assembly).
The first two cases are represented by simple monotonic loss
functions. In the third case, Taguchi adopted a squared-error loss
function for several reasons:
Taguchi’s Specification
13. USUAL APPROACH TO IMPROVE THE QUALITY OF
A PRODUCT OR PROCESS
Identify various causes, known as noise factors, that
degrade the product (process) performance
variations in raw materials and components, machinery,
workmanship, temperature, humidity, loading, etc.
Eliminate the noise factors one by one
14. RESULT OF USUAL APPROACH TO IMPROVE THE
QUALITY OF A PRODUCT OR PROCESS
Eliminating noise factors always leads to
increased costs
Reduction in profitability or loss of market
share in the face of global competition
15. TAGUCHI/ ROBUST DESIGN METHOD
New method of design optimization for
performance, quality, & cost
For existing processes, emphasis is on
parameter design
Smallest, affordable development cost
16. TAGUCHI/ ROBUST DESIGN METHOD
All engineering designs involve setting values
of a large number of decision variables.
Common approach is to study one variable at
a time or by trial and error
Either long and expensive time span for completing
the design / premature termination of the design
process
17. TAGUCHI/ ROBUST DESIGN METHOD
MATHEMATICAL TOOL
Orthogonal arrays to study large number of
decision variables with a small number of
experiments
NEW MEASURE OF QUALITY
Signal to noise (s/n) ratio to predict the quality from the
customer perspective
18. ANALYSIS OF RESULTS
1. To establish the best or the optimum condition for a
product or a process.
2. To estimate the contribution of individual factors.
3. To estimate the response under the optimum
conditions.
21. TAGUCHI/ ROBUST DESIGN METHOD
Many cos. Big or small, high-tech and low-
tech have found the method valuable
High quality at a low competitive price while
maintaining profit margin
22. THE NEW APPROACH –ITS APPEAL AND
LIMITATIONS
Upfront improvement of quality by design
and process development.
Measurement of quality in terms of
deviation from the target (loss function).
Problem solution by team approach and
brainstorming.
23. THE NEW APPROACH –ITS APPEAL AND
LIMITATIONS (CONT.)
Consistency in experimental design and analysis.
Reduction of time and cost of experiments.
Design of robustness into product/process.
Reduction of variation without removing its
causes.
Reduction of product warranty and service costs
by addressing them with the loss function.

26. Why Document?
• Communication Tool
• Manage Change
• Aids consistency
• Record of Best Practice
• Enables Effective Audit
• ISO 9001 Pre-requisite
28. ISO 9001 AND ISO 14001 IN BRIEF
ISO 9001 and ISO 14001 are among ISO's most well
known standards ever.
They are implemented by more than a million
organizations in some 175 countries.
ISO 9001 helps organizations to implement quality
management.
ISO 14001 helps organizations to implement
environmental management.
29. QUALITY MANAGEMENT
ISO 9001 is for quality management.
Quality refers to all those features of a product (or
service) which are required by the customer.
Quality management means what the organization
does to
ensure that its products or services satisfy the
customer's quality requirements and
comply with any regulations applicable to those
products or services.
30. QUALITY MANAGEMENT (CONT.)
Quality management also means what the
organization does to
enhance customer satisfaction, and
achieve continual improvement of its performance.
31. ENVIRONMENTAL MANAGEMENT
ISO 14001 is for environmental management. This
means what the organization does to:
minimize harmful effects on the environment
caused by its activities,
to conform to applicable regulatory requirements,
and to
achieve continual improvement of its environmental
performance.
32. ISO14001 - Environmental management system model for

33. GENERIC STANDARDS
ISO 9001 and ISO 14001 are generic standards.
Generic means that the same standards can be
applied:
to any organization, large or small, whatever its
product or service,
in any sector of activity, and
whether it is a business enterprise, a public
administration, or a government department.
34. GENERIC STANDARDS (CONT.)
Generic also signifies that
no matter what the organization's scope of activity
if it wants to establish a quality management
system, ISO 9001 gives the essential features
or if it wants to establish an environmental
management system, ISO 14001 gives the essential
features.
35. MANAGEMENT SYSTEMS
Management system means what the organization
does to manage its processes, or activities in order
that
its products or services meet the organization’s
objectives, such as
satisfying the customer's quality requirements,
complying to regulations, or
meeting environmental objectives
36. MANAGEMENT SYSTEMS
To be really efficient and effective, the organization
can manage its way of doing things by systemizing
it.
Nothing important is left out.
Everyone is clear about who is responsible for
doing what, when, how, why and where.
Management system standards provide the
organization with an international, state-of-the-art
model to follow.
37. MANAGEMENT SYSTEMS (CONT.)
Large organizations, or ones with complicated
processes, could not function well without
management systems.
Companies in such fields as aerospace, automobiles,
defence, or health care devices have been operating
management systems for years.
The ISO 9001 and ISO 14001 management system
standards now make these successful practices
available for all organizations.
38. PROCESSES, NOT PRODUCTS
Both ISO 9001 and ISO 14001 concern the way an
organization goes about its work.
They are not product standards.
They are not service standards.
They are process standards.
They can be used by product manufacturers and
service providers.
39. PROCESSES, NOT PRODUCTS (CONT.)
Processes affect final products or services.
ISO 9001 gives the requirements for what the
organization must do to manage processes
affecting quality of its products and services.
ISO 14001 gives the requirements for what the
organization must do to manage processes
affecting the impact of its activities on the
environment.
