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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

2. MECHANISMS:
Elements or Links –
Classification – Rigid Link, flexible and fluid link –
Types of kinematic pairs – sliding, turning, rolling, screw and
spherical pairs – lower and higher pairs – closed and open pairs
constrained motion – completely, partially or successfully
constrained and incompletely constrained.
Gubralrs criteria, Grashoff’s law,
Degrees of freedom, Kutzbach criterian for planar mechanisms,
Mechanism and machines – Classification of machines –
kinematic chain –
inversion of mechanism –inversions of quadric cycle, chain –
single anddouble slider crank chains.
8. Classification of Links
• 1. Rigid link
A rigid link is one which does not undergo any deformation while
transmitting motion
• 2. Flexible link
A flexible link is one which is partly deformed in a manner not to
affect the transmission of motion
• 3. Fluid link
A fluid link is one which is formed by having a fluid in a receptacle
and the motion is transmitted through the fluid by pressure or
compression only, as in the case of hydraulic presses, jacks and
brakes
9. KINEMATIC PAIR
• The two links or elements of a machine, when
in contact with each other, are said to form a
pair. If the relative motion between them is
completely or successfully constrained (i.e. in
a definite direction), the pair is known as
kinematic pair.
10. Classification of Kinematic Pairs
1. According to the type of relative motion
between the elements
•(a) Sliding pair
•(b) Turning pair
•(c) Rolling pair
•(d) Screw pair
•(e) Spherical pair
11.
12. (a) Sliding pair
• Piston And Cylinder
• Cross-head And Guides Of A Reciprocating Steam Engine,
• Ram And Its Guides In Shaper,
• Tail Stock On The Lathe Bed Etc.
13. (b) Turning pair
• A Shaft With Collars At Both Ends Fitted Into A Circular Hole
• The Crankshaft In A Journal Bearing In An Engine
• Lathe Spindle Supported In Head Stock
• Cycle Wheels Turning Over Their Axles Etc
16. • 2. According to the type of contact between the
elements
• (a) Lower pair
• (b) Higher pair
• 3. According to the type of closure
• (a) Self closed pair
• (b) Force - closed pair
18. Types of Constrained Motions
1. Completely constrained motion
When the motion between a pair is limited to a definite
direction irrespective of the direction of force applied, then the
motion is said to be a completely constrained motion.
Fig: Shaft in a circular hole Fig: shaft with collars in a circular hole
19. 2. Incompletely constrained motion
When the motion between a pair can take place in more than
one direction, then the motion is called an incompletely
constrained motion.
Fig:Square bar in square hole
20. 3. Successfully constrained motion
•When the motion between the elements, forming a pair, is such
that the constrained motion is not completed by itself, but by
some other means, then the motion is said to be successfully
constrained motion

21. • It is defined as the number of input parameters (usually pair
variables) which must be independently controlled in order to
bring the mechanism into a useful engineering purpose.
Number of Degrees of Freedom
for Plane Mechanisms
22. Kutzbach Criterion to Plane
Mechanisms
• Kutzbach criterion for determining the number of degrees of
freedom or movability (n) of a plane mechanism is
n = 3 (L – 1) – 2 j – h
23. • 1. The mechanism, as shown in Fig. (a), has three links and three binary joints, i.e. l =
3and j = 3.
n = 3 (3 – 1) – 2 × 3 = 0
• 2. The mechanism, as shown in Fig. (b), has four links and four binary joints, i.e. l = 4
and j = 4.
n = 3 (4 – 1) – 2 × 4 = 1
• 3. The mechanism, as shown in Fig. (c), has five links and five binary joints, i.e. l = 5,
and j = 5.
n = 3 (5 – 1) – 2 × 5 = 2
• 4. The mechanism, as shown in Fig. (d), has five links and six equivalent binary joints
(because there are two binary joints at B and D, and two ternary joints at A and C),
i.e. l = 5 and j = 6.
n = 3 (5 – 1) – 2 × 6 = 0
• 5. The mechanism, as shown in Fig (e), has six links and eight equivalent binary joints
(because there are four ternary joints at A, B, C and D), i.e. l = 6 and j = 8.
n = 3 (6 – 1) – 2 × 8 = – 1
24. Grubler’s Criterion for Plane
Mechanisms
• The Grubler’s criterion applies to mechanisms with only single degree of freedom
joints where the overall movability of the mechanism is unity.
• Substituting n = 1 and h = 0 in Kutzbach equation, we have
• 1 = 3 (l – 1) – 2 j or 3l – 2j – 4 = 0
25. • Difference Between a Machine and a Structure
• Kinematic Chain
When the kinematic pairs are coupled in such a way that the last link is
joined to the first link to transmit definite motion (i.e. completely or
successfully constrained motion), it is called a kinematic chain.
26. Inversions of Four Bar Chain (or)
Quadric Cycle Chain
According to Grashof ’s law for a four bar mechanism, the sum of the shortest and
longest link lengths should not be greater than the sum of the remaining two link
lengths if there is to be continuous relative motion between the two links.
