The interaction of a single particle in straight rectangular channel in laminar flow is modelled explicitly using the set of Navier Stokes equation for the fluid motion and Newton momentum equation for the particle motion in Cartesian coordinate system. The evaluation of integral force acting on the particle along with the behaviour of streamlines as a function of Reynolds number ReP < 120 is ...

The paper provides an overview of the state of art in computational electromagnetic. There are three major ar eas like Design, optimization and material selection for the electric machines. The computational tool based on finite elements is very useful and powerful field simulation techniques available to assist in the design and performance prediction of electric machines. But the complexity in ...

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a Software. It is shown that the Fitzhugh-Nagumo equations allow for a geometrical explanation of important ...
COMSOL® Implementation of a Viscoelastic Model with Cure-Temperature-Time Superposition for Predicting Cure Stresses and Springback in a Thermoset Resistant
 General Motors Global Research and Development, India Science Lab, GM Technical Centre India.
Multi-physics simulations of the evolution of cure induced stresses in a viscoelastic thermoset polymeric resin are presented. The viscoelastic material model is implemented with a relaxation spectrum with 34 relaxation time constants. The trends in viscoelastic stresses at different degrees of cure and temperatures are compared and contrasted with an equivalent cure–dependent (but ...

Steam drums of a nuclear power plant separate steam from the steam water mixture and sub cooled incoming feed water returns to the reactor. The entire feed water flow is delivered to the steam drum through the feed water sparger. The feed water sparger is provided with number of inverted ‘j’ type lateral tubes to distribute the feed water in the drum for proper mixing with the separated ...

The majority of electrical machines are designed to produce the rotary motion, there by exploiting the blessing of circularity which man has enjoyed since the discovery of the wheel. Electromagnetic forces may also be employed to produce the linear motion resulting in linear motion electrical machines. The performance of a high speed LIM is severely degraded by "End Effects". The paper provides ...

Surfaces with water contact angle greater than 150º are super-hydrophobic in nature and possess extraordinary water repelling properties. Various researches on wettability of textured surfaces in recent years have shown that texturing surfaces with micron-sized and nanosized patterns improves their hydrophobicity to a great extent. This report aims at optimizing the dimensions of ...

A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO 3) in CO/CO2 atmosphere. The proposed mechanism involves diffusion of CO gas through the ores of the ...

The purpose of this paper is to illustrate the microwave coagulation therapy (MCT) that can be used mainly for the treatment of hepatocellular carcinoma. In this treatment invasive technique are used in which thin microwave coaxial antenna is inserted into the tumor and the microwave energy heats up the tumor to produce the coagulated region including the cancer cells. We have to heat the cancer ...
