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.

• Production centre to market centres
• Employment
• Imports and exports
• Industrial and agricultural production
• Education and health care
• Natural calamities assistance
• Defence system
• Improved life style of people
• Control of anti-social activities
15. BASIC IDEALIZATIONS
• Particle (only mass, no size. Ex: aeroplane in sky, ship on sea)
• Continuum (continuous distribution of matter)
• Rigid body (no change in relative positions of any two particle)
• Point force (weight of body is considered as a single force, ignoring the area of
contact)
16. Force & System of forces
A force is an agency which tries to change state of rest or state of uniform
motion of the body
Elements of a force:
• Magnitude
• Point of application
• Line of action
• Direction
18. Basic principles
• Principle of Physical independence of forces
“The action of a force on a body is not affected by the action of any other force on the body”
• Principle of Superposition of force
“The effect of a given system of forces on a rigid body is not changed by adding or
subtracting another system of forces in equilibrium”
• Principle of Transmissibility of forces
“The state of rest or motion of the body is unaltered if a force acting on a rigid body is
replaced by another force of the same magnitude and direction but acting anywhere on the
body along the line of action of the replaced force”
19. Newton laws of motion
• First law
“Every body continues in its state of rest or motion in a straight line unless it is compelled by
an external agency on it ”
• Second law
“The rate of change of momentum of a body is directly proportional to the impressed force
and it takes place in the direction of the force acting on it. (F α m.a) ”
• Third law
“For every action there is an equal and opposite reaction”
20. RESOLUTION OF A FORCE
• The process of splitting a force acting on a particle into multiple components
without changing the effect of the single force.
• Note: If the force F makes an angle θ with vertical axis, then
Fx = F Sin θ
Fy = F Cos θ
Fx = F Cos θ
Fy = F Sin θ
21. COMPOSITION OF FORCES
• The process of combining a number of forces into a single force such that the
net effect produced by the single force is equal to the algebraic sum of the
effects produced by the individual forces.
22. Methods of finding Resultant
1. Parallelogram law
“If two forces are acting simultaneously on particle and away from the particle,
with the two adjacent sides of the parallelogram representing both the
magnitude and direction of forces, the magnitude and direction of the resultant
can be represented by the diagonal of the parallelogram starting from the
common point of the two forces”
23. Methods of finding Resultant
2. Triangle law
“If two forces are acting simultaneously on a particle can be represented both in
magnitude and direction by the two sides of a triangle taken in order, then the
magnitude and direction of the resultant can be represented by the closing side
of a triangle, taken in opposite order”
24. Methods of finding Resultant
3. Polygonal law
“If a number of forces acting on a particle can be represented in both magnitude
and direction by the sides of the polygon taken in order, then the resultant can
be represented in magnitude and direction by the closing side of the polygon
taken in opposite order”
25. Moment of a force
• The rotational effect produced by a force on a body is known as the moment of
the force.
• Magnitude of moment is given by the product of the magnitude of the force
and the perpendicular distance between the line of action of the force and the
point of rotation.
• The point about which moment is considered is called moment centre.
• The perpendicular distance of the point from the line of action of the force is
called moment arm.
Note: Moment of a point lying on the line of action is ZERO
27. Varignon’s theorem of moments
“The algebraic sum of the moments of individual forces of a force system about
a point is equal to the moment of their resultant about the same point”
28. COUPLE
• “Two parallel forces equal in magnitude and opposite in direction and
separated by a definite distance are said to form a couple”
Note: Moment of a couple about any point is same.
29. Resultant of coplanar concurrent force system
For coplanar concurrent two force system:
R = (𝐏𝟐 + 𝐐𝟐 + 𝟐𝑷𝑸 𝑪𝑶𝑺𝜽)
α = 𝒕𝒂𝒏−𝟏(
𝑸 𝑺𝒊𝒏𝜽
𝑷+𝑸 𝑪𝒐𝒔𝜽
)
For coplanar concurrent force system:
R = 𝜮𝑭 𝒙
𝟐 + 𝜮𝑭 𝒚
𝟐
α = 𝒕𝒂𝒏−𝟏
(
𝜮𝑭 𝒚
𝜮𝑭 𝒙
)
