Heat Transfer and Phase Change

Multiphysics Modeling of a Grain Storage Chamber

P. Guha[1], P. Sharma[1], V. Malhotra[1], S. Mishra[1]
[1]CSIR - Central Scientific Instruments Organisation, Chandigarh, India

Proper storage of grains depends on minimizing attacks of insects, fungi, mites, etc. Development of such pests can be controlled by controlling the temperature of the storage chamber. Hence, before designing grain storage chambers, mathematical modeling and numerical simulations should ... En savoir plus

Implementation of a Viscoelastic Material Model to Simulate Relaxation in Glass Transition

Z. Zheng[1], R. Zhang[1]
[1]Corning Incorporated, Corning, NY, USA

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. ... En savoir plus

Heat Transfer in Crossflow Heat Exchangers for Application with Microreactors

R. Pryor[1]
[1]Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

This paper explores methods of improving the heat transfer coefficient in a crossflow heat exchanger as would be employed in conjunction with an experimental or production microreactor. This derivation of the Cross-Flow Heat Exchanger from the COMSOL Multiphysics® software Model Library ... En savoir plus

Study of the Process, Design, and Operating Parameters Effect on the Efficiency of the Process Mill

A. K. Farouk[1]
[1]Department of Mathematics & Natural Science, University of Stavanger, Sandnes, Rogaland, Norway

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers ... En savoir plus

Enhanced Transient Modeling of Hybrid Photovoltaic Air (PVT) Module

R. Kiflemariam[1], M. Almaz[1], F. Zevallos[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air ... En savoir plus

Modeling Integrated Thermoelectric Generator-Photovoltaic Thermal (TEG-PVT) System

R. Kiflemariam[1], M. Almas[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

2D steady state heat conduction-electric current model was created in COMSOL Multiphysics® software to study the performance of thermoelectric generator-photovoltaic-thermal (TEG-PVT) system. Four different cases were studied in the paper. In case 1, PV cells without concentrator was ... En savoir plus

3D COMSOL Multiphysics® Model of a Plate Heat Exchanger to Support a Laboratory Teaching Environment

N. Medeiros[1], W. Clark[1]
[1]Worcester Polytechnic Institute, Worcester, MA, USA

Chemical engineering students and practitioners need an understanding of fluid flow and heat transfer inside heat exchangers. Because the flow within plate heat exchangers is difficult to visualize, we developed COMSOL Multiphysics® simulations of plate heat exchangers for students to ... En savoir plus

A Computational Study on Thermal Conductivity Measurements of High Temperature Liquid Materials

X. Ye[1], R. W. Hyers[1]
[1]Department of Mechanical & Industrial Engineering, University of Massachusetts - Amherst, Amherst, MA, USA

Accurate thermo-physical properties of materials are valuable for both scientific research and industrial applications. For high temperature liquid materials, two issues exclude traditional methods: elevated reactivity of test material and experimental apparatus, uncontrolled heat ... En savoir plus

Passive Thermal Control for Window Insulation

E. Konroyd-Bolden[1], Dr. Z. Liao[1]
[1]Department of Architectural Science, Ryerson University, Toronto, ON, Canada

A requirement of the building envelope is to act as environmental separator. Energy is one component that we sometimes wish to control. How can this yield passive benefits such as solar heating? This research focuses on control of thermal radiation energy, and the role windows play ... En savoir plus

Modeling Flow and Deformation During Salt-Assisted Puffing of Single Rice Kernels

T. Gulati[1], A. K. Datta[1]
[1]Department of Biological & Environmental Engineering, Cornell University, Ithaca, NY, USA

Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. ... En savoir plus
