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.

11. WhaT is sMaW?WhaT is sMaW?
It is a welding process which joins metals by heating the metals to their
melting point with an electric arc set up between the end of a coated metal
electrode and the work piece.
Molten metal droplets and the molten weld are shielded from the
atmosphere by the gases produced from the decomposition of the flux
coating .
12. saW prOcess principles
SAW is a welding process which joins metals by heating the metals to their melting
point with an electric arc or arcs set up between a bare metal electrode and the job.
The arc, the end of electrode and molten pool remains completely hidden and are
invisible being submerged under a blanket of granular flux.
The continuously fed bare metal electrode melts and acts as filler rod.
13. SAW Features

14. Gas Metal Arc ( MIG )
Welding
Uses continuous wire 0.6 – 2.0
mm as electrode
Gas shielded, inert or active gas
Manual, automatic or semi-
automatic process
High productivity
If the wire feed speed is
increased more current is drawn
to burn it off .
Increasing the current increases
the arc energy and therefore the
heat input. This in turn increases
fusion and penetration, wire
deposition rate and travel speed.

26. machines in area b
flame cuTTing cnc laser cuTTing
Steel plates are ultrasonically tested
before being precision cut by
numerically controlled flame
cutting machines or by CNC
LASER machine.
The laser beam is typically 0.2
mm (0.008 in) diameter at the
cutting surface with a power of
1000 to 2000 watts.
Lasers work best on materials
such as carbon steel or stainless
steels because these are difficult
to cut due to their ability to
reflect the light as well as
absorb and conduct heat. This
requires lasers that are more
powerful.
