A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the simulation and Rosenthal’s solution, when the geometry of the domain and the source are changed, has been ...

De Laval nozzles are used in supersonic aerodynamical tubes and engines. They are also employed for the production of cold gas jets to be used in chemical reactions studies. Recently, cold gas jets have been proposed of In-Gas Laser ionization Spectroscopy (IGLIS) The nozzle has a converging and a diverging part with a throat between them. High gas pressure and temperature, and low velocity ...

A dynamic mathematical model, based on physical and transport properties and mass and energy balances, was developed for the simulation of unsteady convective drying of agricultural products (fruits and vegetables) in static bed conditions. The model utilizes water sorption isotherm equations and the change in solid density due to the shrinkage phenomenon. The aim of this article is to describe ...

This paper presents a simulation approach to develop a model for understanding the mixing phenomenon in a stirred vessel. The mixing in the vessel is important for effective chemical reaction, heat transfer, mass transfer and phase homogeneity. In some cases, it is very difficult to obtain experimental information and it takes a long time to collect the data. Such problems can be solved using ...

2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The governing equations are solved applying the COMSOL Multiphysics® interfaces Laminar flow, Electric Currents, ...

The MEMS microphone is also called microphone chip or silicon microphone. The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. The MEMS microphone has been successfully fabricated and tested in an anechoic chamber. The microphone ...

The coaxial cable is one of the most commonly used bandwidth limited signal transmission line.Dispersion is a signal distortion phenomenon which arises due to frequency dependence of phase velocity of signal components. This phenomenon was explained through time domain approach by studying time taken by signals of various frequencies to propagate through the cable, which eventually may cause ...
