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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
3. HARDWARE
Hardware is the physical components of the
computer system which you can touch. An
example of hardware is the system unit others are
printer, scanner, speaker, mouse, keyboard etc.
4. Computer hardware is divided into two main
categories: the system unit and peripherals.
The system unit. The system unit is the main enclosure or case of
computer that houses the internal hardware components.
The system unit provides physical protection for these components.
These components include the central processing unit, primary
memory, and the system board.
6. Internal Hardware components
Internal components of computer hardware refer to the physical
parts inside a system unit.
Motherboard
Central Processing Unit (CPU)
RAM Memory (Random Access Memory)
Graphics Processing Unit (GPU)
Cooling System
etc.
7. MOTHERBOARD
Motherboard is the main circuit board inside a computer that
connects all the internal hardware components together.
The motherboard distributes Power to all the connected components,
ensuring they receive the appropriate voltage and current.
10. Central Processing Unit (CPU)
The brain of any computer system is the CPU. It controls the
functioning of the other units and process the data.
The CPU executes the program by processing each piece of data as
directed by the program and the instruction set.
11. The Components of CPU
A typical CPU has three major components:
1. Register Set.
2. Arithmetic Logic Unit (ALU).
3. Control Unit (CU).
12. 1. The Register Set
CPU registers perform a variety of functions, a primary one of
which is to offer temporary storage for the CPU to access
information stored on the hard drive.
2. Arithmetic and logic unit (ALU)
Arithmetic perform Arithmetic operations like addition, subtraction,
multiplication, division etc.
The logic unit is responsible for performing logical operations such
as comparing, selecting, matching and merging of different data or
information.
13. 3. Control unit
The control unit is the main coordinator which controls all the
operations of the different units.
Control unit is also responsible for communicating with all input
and output devices for transferring or receiving the instruction from
the storage units.
14. RAM Memory (Random Access Memory)
RAM is the temporary storage for data and programs that are being
accessed by the CPU.
RAM is volatile memory, which means that the contents are erased
when the computer is powered off. The more RAM in a computer,
the more capacity the computer has to hold and process large
programs and files.
15. Cooling system
Cooling systems are designed to regulate and keep cool Computer
components so as to maintain optimal performance and protect the
computer from damage. If too much heat builds up, computer
components can be damaged.
16. Graphic Processing Unit
A graphic Processing Unit (GPU) is responsible for graphic quality
of items being displayed on a monitor through reading graphics
software (such as drives) established on the computer.
18. External Hardware Components
(Peripheral Components)
External hardware components are those items that are often externally
connected to the computer to control either input or output functions.
Monitor Camera
Touchpad Printer
Mouse USB flash drive
Gaming control Speaker
Headphones External Hard Drive
Data Projector Keyboard
Microphone

Output devices are computer hardware that receive data from a
computer and then translates that data into visual, textual or hard
copy such as a printer document.
MONITOR
Monitor- a monitor displays data from a computer onto a screen so
the user can interact with the data. A monitor is an output device that
displays information visually.
27. PRINTER

instruction is sent from the computer to the printer transforming
onto paper.
28. PROJECTOR
Projector- a projector is an output device that projects computer
images or video onto a wall or screen.
29. SPEAKER
Speaker- speaker are hardware device that transform the signal
from the computer´s sound card into audio. Speakers create sound
using internal amplifiers that vibrate at different frequencies
according to data from the computer.
30. Hard Drives
Internal Hard Drive
Internal hard Drive- an internal hard drive is a data storage device
that is installed inside a computer.
31. External Hard Drive
