3D Unsteady CFD Simulation of Seasonal Solar Thermochemical Heat Storage System for Buildings

W. Yaïci [1], E. Entchev [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Read More

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Read More

Thermal Bridging Calculation of Three Steel Stud Wall Assemblies with Benchmarking

M. Ghobadi [1],
[1] National Research Council Canada, Ottawa, ON, Canada

As a part of the Pan-Canadian framework for clean growth, Canada is intent on meeting its 2030 emission targets for which 17% of Canada’s total Green House Gas emissions come from buildings. Given this challenge, emphasis is being placed on developing building designs having greatly ... Read More

Simulation of Laser Powder-bed Fusion Additive Manufacturing Process Using the COMSOL Multiphysics® software

K. Leung [1], A. Imanian [1],
[1] Technical Data Analysis, Inc., Falls Church, VA, USA

Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... Read More

Nonhomogeneous Heat Transfer Simulation Using a Female Human Model

M. Castellani [1], T. Rioux [1], X. Xu [1],
[1] U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA

Previously researchers have modeled the human body using CAD software to create geometries that are approximately the same shape as the human body. While these CAD designs appear similar, they do not account for complex organ anatomy or sudden changes at the skin surface. Now, the human ... Read More

Multiphysics Simulation of 2nd Generation 238Pu Production Designs Using the COMSOL Multiphysics® software

C. J. Hurt [1], J. D. Freels [1], A. Elzawawy [2],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA

In order to qualify experiments for in-vessel irradiation at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, safety assessments need to be completed and documented to ensure adequate target cooling and structural integrity. Previously, finite element analysis ... Read More

Multidisciplinary Simulation Based Learning Enhancement Module

A. K. Datta [1], M. Ukidwe [1], A. Warning [1], K. Bhunia [1],
[1] Cornell University, Ithaca, NY, USA

Simulation based learning modules can be effectively introduced to a large audience with customization. The simulation modules can essentially engage learners from diverse background and efficiently introduce the quantitative approaches to non-engineers. Moreover, those can greatly help ... Read More

Modeling Heat Transfer Through Filament Yarns by Random Geometry Creation

N. Anand [1], W. J. Jasper [1], E. DenHartog [1],
[1] North Carolina State University, Raleigh, NC, USA

Filament yarns are a collection of microfibers of set diameter and material held together by tension and/or intra-filament attraction. This results in a stacking patterns which can be random with different degrees of freedom. A slight change in tension or attractive forces may mean a ... Read More

Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization

A. Ward [1],
[1] System Insight Engineering, Centennial, CO, USA

As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Read More

Evaporative Cooling in Solar Absorption Chiller

J. Ma [1], M. J. Suh [1],
[1] Sam Houston State University, Huntsville, TX, USA

Solar cooling systems based on evaporation and absorption processes have been actively studied and different mechanisms based on various refrigerants are designed and developed. Amongst these systems, a single-stage close cycle design utilizing lithium bromide salt and water (LiBr-H2O) ... Read More
