Design, Simulation, and Fabrication of Thermal Angular Accelerometers
This abstract introduces a sensor design for detecting angular acceleration in a single plane using thermal convection. The working principal of the device is based on probing temperature profile changes along a micro-torus caused by angular acceleration. By properly choosing the ... Read More
CFD Analysis of a Printed Circuit Heat Exchanger
In this experiment, the performance of a Printed Circuit Heat Exchanger (PCHE) was studied using COMSOL Multiphysics® software. PCHEs are diffusion bonded heat exchangers containing semicircular, chemically etched flow paths. Helium was used as the working fluid on both the hot and cold ... Read More
Modeling of Stockton University Geothermal System Using COMSOL Multiphysics® and the Subsurface Flow Module
Stockton University has one of the largest closed loop geothermal system in North America. It provides heating and cooling for the university academic facilities. The well field comprises of a grid of four hundred wells bored to a depth of 130m. The ground is composed of three aquifers ... Read More
2D Axisymmetric Temperature Profile Modeling of a Delayed Coking Drum During Pre-Run Warm Up
Delayed Coking is a refining process, which takes heavy petroleum residue as a feed. A 2D axisymmetric stationary model was created to simulate this pre-run condition with nitrogen gas, as an attempt to calibrate the model before simulating with an oil residue. The single-phase laminar ... Read More
Heat Transfer and Phase Change Simulation in COMSOL Multiphysics® Software
This session is devoted to phase change modeling in heat transfer simulations. The great interest in phase change comes from the outstanding thermal performance that it enables in particular for cooling or thermal protection applications. Alternatively, phase change can induce most of ... Read More
Thermal-Optical Modeling of a Signal Enhancement Approach for Paper-Based Diagnostics
INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... Read More
Multi-Dimensional Simulation of Flows Inside Mono and Polydisperse Packed Beds
An analysis to quantify the flow inside the narrow channels of an ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) adsorbent bed is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Heaters and associated fins inside ... Read More
Multi-Dimensional Adsorption Model of CO2/H2O Sorbent Bed
The primary interest of the VC (Vacuum Characterization) test is to experimentally characterize the adsorption and vacuum desorption of CO2 and water vapor of a pelletized sorbent bed in a large diameter column. The VC test article is shown in Figures 1 and 2. The aluminum canister is 3” ... Read More
Mitigation of Greenhouse Gas Leakage from Oil and Gas Wells
Pre-existing oil and gas wells and well bores represent highly permeable pathways for leakage of greenhouse gases; in Alberta alone leaks have been estimated to provide the equivalent of 3.5 million tonnes of CO2 per annum. In addition to abandoned wells without plugs, gas leakage may ... Read More
Multiphysics Analysis of an Infrared Bolometer
Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The general principle of operation is shown below: a strip of conducting material is exposed to incident ... Read More
