Heat sinks for cryogenic applications using helium gas as the coolant are not readily available. They require to be designed specifically for the intended application. A finite element model was developed to study the feasibility and optimize the design. The FEM computing package COMSOL ... En savoir plus
The radiation dose produced by an x-ray CT scanner to the patient is conventionally referenced to measurements performed by an ionization chamber in a phantom. On a fundamental level, the radiation absorbed dose, J/kg, can be determined directly by the temperature rise in the absorbing ... En savoir plus
An FEA model of a steady state thermal interface material characterization apparatus was created in COMSOL Multiphysics 4.2a. This model was then fitted using three convection heat loss coefficients and the conductance of the TIM layer to a set of experimental measurements made using a ... En savoir plus
This project utilizes the heat transfer module of the COMSOL Multiphysics environment to model the effects that an ohmic heating probe will have on neural tissue. The model quantifies the thermal impact of active components embedded on a neural micro probe by solving the Penne’s bioheat ... En savoir plus
In 2010 an estimated 109 million infants were immunized against DTP, which serves as a good proxy for vaccinations in general. At the same time, however, approximately 19.3 million infants worldwide were not reached by routine DTP immunization services. Immunization rates tend to be ... En savoir plus
Simulation of criticality accident transients offers the ability to confirm understanding of critical configurations, bound accident scenarios and aid comprehensive emergency planning. Computational ability to recreate excursion power histories in fissile solution is sought due to the ... En savoir plus
A fully coupled multiphysics model involving heat transfer and groundwater flow within a SCW and its surrounding ground was implemented in COMSOL Multiphysics 4.2a with MATLAB to simulate a 24-hour heating operation. The heat pumps were modeled using interpolation functions thereby ... En savoir plus
Photovoltaic systems can degrade with moisture. The addition of an edge-seal containing a desiccant can reduce the amount of water reaching the interior. This report discusses the modeling of the water transport into the system to determine the amount of edge seal and desiccant ... En savoir plus
COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is ... En savoir plus
Quenching from high temperature by fluid flow has been analyzed; when no phase transformation occurs heat transfer is a function of conduction and convection. Flow conditions may lead to turbulent flow that affects the heat dissipation over the surface. Analysis of heat transfer with ... En savoir plus
