The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map the tab to establish its thermal mapping. This led us to perform simulations at each ASIC of the tab that ...

A multilayer polymer coating is applied to carbon steel pipelines installed in the sea to protect against corrosion and to insulate to maintain the temperature. For field joint coatings, both thermosets (like polyurethane) and semi-crystalline thermoplastics (like polypropylene) are commonly used. To predict the temperature and crystallinity or conversion of the polymer during the cooling ...

PEM Fuel Cells’ durability and performance can be increased using an ejector based hydrogen recirculation system. In this work, a CFD model has been implemented to simulate the flow within an ejector used to recirculate hydrogen in PEM Fuel Cell systems. The model has been validated experimentally and has been used to design and manufacture an ejector that will be implemented in a fuel cell test ...

PCR (Polymerase Chain Reaction) is a recent well researched technique which can be employed to obtain an amplified DNA (Deoxyribonucleic Acid). A continuous flow polymerase chain reaction with integrated MEMS based design micro heater for DNA amplification is implemented. Temperature zone is obtained by natural heat conduction rather than making use of typical silicon thermal cycler. Inter ...

This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver. The principle of our pore-scale modeling approach is composed of two steps. The first step involves the detailed identification and specification of the porous medium morphology, this step was ...

Introduction: One of the main characteristic of the superconductors is its diamagnetic response of applied magnetic fields. The superconductors refuse the penetration of magnetic field into its interior, it is the well know Meissner effect, B=0 into the superconductor sample. However when the applied field reach a determined value, the magnetic field can enter. There are two different ways of ...

The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment while holes pull cells toward the surface and increase residence time on the surface increasing attachment rate.

A two-dimensional steady model of the natural convection around a cylinder is solved numerically using COMSOL Multiphysics software. The cylinder receives non-uniform heat from a radiating panel, which is assumed to be sufficiently far away so that the flow around the panel does not interfere with the cylinder. Changes in temperature and velocity are monitored for varying heating rates and ...

Bionics is the scientific discipline between biology and technology. The aim of bionics is to recognize natural design principles and derive technical solutions. Natural structures have been optimized over generations by evolution. In most cases the minimization of the energy demand is a major intend of natural optimization. There are different designs of heat exchangers, e.g. parallel or ...

This paper deals with the simulation of mathematical model for supercritical extraction. Reverchon, 1996 extracted sage oil using supercritical extraction method from sage leaves at 9 MPa and 50 ᵒC. Four mean size of sage leaves ranging from 0.25 to 3.10 mm were taken for extraction with other experimental conditions and process parameters. Experimental results were fitted in the model developed ...
