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.

Editor's Notes
Prepared by Jim Giammanco
<[email_address]>
Students will learn to identify the most commonly used electronic components and to determine component values by interpreting the manufacturer’s markings. Students will also learn the precautions needed to protect components from electrostatic discharge, as well as when it is important to observe the polarity of a component when it is installed into a circuit.
There have been various other ditties used in the past to remember the color code. Most are unsuitable for polite company.
When the tolerance band is not present, 20% tolerance is assumed.
Some precision resistors will have three “significant digit” bands before the multiplier band.
Good practice is to select a resistor whose power rating is at least two or three times the expected power dissipation. For most low power, low voltage circuits, ¼ watt resistors are appropriate. The three 10% tolerance carbon composition reistors shown are (top to bottom) ½ watt, 1 watt, and 2 watt. Their values are 3.9M, 47K, and 390K. The two smaller resistors are ¼ watt, the top is carbon film, 200Ω 5%, and the bottom is metal film, 47K 2%.
The nanofarad (nF) is commonly used in Europe, but that nomenclature is rare in USA and Canada.
Polarized capacitors are often referred to as electrolytics because the plate and dieletric structures are formed by a chemical reaction involving an electrolyte.
Ceramic disk – 471J means 47 x 101 pf, or 471 pF, the J stands for 5% tolerance
Monolithic ceramic – 102 means 10 x 102 pf or 1000 pf, or 0.001 μF
Dipper mico – 220 means 220 pF
Mylar (left) - .005 means 0.005 μF
Mylar (right) – 223 means 22 x 103 pF or 22000 pF or 0.022 μF
Solid tantalum – 1 35 means 1 μF at 35 WVDC
Radial aluminum – as marked 100 μF at 50 WVDC
Axial aluminum – as marked 100 μF at 35 WVDC
Ferrite and iron powder inductor cores are often made in the form of toroids, since a toroidal coils is self-shielding, that is, its magnetic flux is confined to the interior of the core. Toroidal transformers are widely used in high frequency circuits because of this self-shielding property.
The molded inductor is marker brown-black-black-gold, meaning 10 x 100 μH, or 10 μH, with 5% tolerance.
Other inductor types are often unmaked, with value indcated on packaging materials only.
Early diodes were vacuum tube devices. Now, almost all are semiconductors.
Symbols are, left to right, a light emitting diode (LED), common diode, and zener diode.
The arrow on the symbol represents the cathode (negative) lead, and the bar represents the anode (positive) lead.
In effect, the arrow points in the direction of conventional current flow (positive charge motion)
The cathode (negative) lead of the cylindrical diodes is denoted by the banded end.
Note the flatted side of the LED. This usually denotes the cathode (negative) end of the diode. Often the anode (positive) lead will be slight longer than the cathode lead.
The first transistor was fashioned at Bell Labs in 1948.
The circuit symbols are, left to right,
- NPN bipolar junction transistor (BJT)
- PNP bipolar junction transistor
- N channel junction field effect transistor (JFET)
- P channel junction field effect transistor
- P channel metal oxide on semiconductor, insulated gate, field effect transistor (MOSFET or IGFET)
- N channel metal oxide on semiconductor, insulated gate, field effect transistor
Pinouts may vary from manufacturer to manufacturer. It is always best to consult the data sheets.
For the TO-18 package, the lead near the small tab on the can is almost always the emiiter.
The physical size of the package affect the power dissipation capability of the devices. TO-92 and TO-18 packages are limited to a few tens or hundreds of miliiwatts. The TO-220 package can dissipate several watts.
Pictured is a “CANSAT” circuit board, forerunner of the “BALLOONSAT” flight computer board.
When the label on the chip reads correctly from left to right, pin 1 will be in the lower left corner of the chip.
This is a DIP-14 package, meaning “dual-in-line, 14 pin”
