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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. Manufacturing
Arrived from the Latin word
“manu factus”, meaning “made
by hand”.
Manufacturing is the process of
converting raw materials into
products.
4. WHY STUDY
MANUFACTURING PROCESSES?
The designer and the drafter
must have a working knowledge
of the various processes that
could produce a part in order to:
lower cost and reduce
production time.
5. Three Phases Of The
Manufacturing Process
1. Product design.
2. Selection of materials.
3. Selection of production
methods and techniques.
6. The information needed to produce a
part, most often comes in the form of a:
Working Drawing
7. Three Main Stages Of The
Production Of A Machined Part
Rough Forming
Casting, Forging, Welding
Finishing
Drilling, machining, surfacing
Assembling
The assembly of parts
8. The Casting Process
First a pattern is made.
Then a cavity is made by placing a pattern in
wet sand.
Next molten metal is poured into the cavity of
damp sand.
9. The Casting Process
The rough casting is now ready for the machine shop.
Holes are then bored and reamed.
Top and bottom surfaces are machined
Smaller holes will be drilled and counterbored.
All corners on cast parts are fillets and rounds.
Rough
Casting
Machined
Finish
10. Forging Process
Forging is produced by using heavy mechanical
presses or hammering heated bars of metal
between dies.
Advantages of forging over sand casting are that
forged parts are much stronger and less brittle.
11. Welding
Welding is the fusion or joining of
two pieces of metal by means of
heat, with or without the application
of pressure.
Cast
Welded
13. Metals are classified as:
Ferrous - contain iron and steel.
Nonferrous - do not have iron content
(such as copper and aluminum).
Alloys - mixture of two or more metals.
14. Inorganic Materials Include:
• Carbon and graphite - have low
tensile strength (ability to be
stretched).
• Ceramics are clay and glass
materials. (resistant to heat,
chemicals, & corrosion).
15. Heat-Treating:
Annealing – is the process generally used
to soften metal by heating followed by slow
cooling.
Hardening – requires heating and then
rapid cooling in oil or water.
16. Plastics Processing
The plastics industry represents one of the
major manufacturing segments.
Thermoplastic – becoming or remaining
soft and moldable when subjected to heat.
Thermosetting – becoming permanently
hard and unmoldable when once subjected
to heat.
18. Extruding
The process of producing
shapes by forcing hot metal
through a die that has and
opening of the desired shape.
19. Blow Molding
Used in the production of
bottles, automotive ductwork,
hollow toy components, and
door panels.
20. Injection Molding
Used to manufacture products such
as housings for electronic
implements, automotive components,
food storage containers, and
components for medical applications.
.
21. Thermoforming
Used in the manufacturing of thin-walled
packages for the food industry.
Manufactured primarily by injection molding.
22. CAD in Manufacturing
The process of developing a design drawing on a
CAD system and producing it on a computerized
machine is called CAD/CAM.
The process of converting the CAD drawing into a
preprogrammed, coded instructions is called
Computer Numerical Control (CNC).
The advantages of the (CNC) is, better production and
control, increased productivity, decreased labor and
lower production costs.
23. The Machinist Steel Ruler
Commonly used measuring tool for getting
rough measurements on a part.
The smallest division on the fractional
scale is 1/64” (.016).
24. Vernier Caliper
