In order to achieve an optimized design of the Multi-Lumen Thoracic Catheter (MLTC), fluid dynamics analyses were conducted utilizing COMSOL Multiphysics® software with LiveLink™ for Solidworks®. Lumen placement, diameters, and termination points were adjusted to ensure maximum drainage ... Read More

Delayed Coking is a refining process, which takes heavy petroleum residue as a feed. A 2D axisymmetric stationary model was created to simulate this pre-run condition with nitrogen gas, as an attempt to calibrate the model before simulating with an oil residue. The single-phase laminar ... Read More

Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...

We have developed single leg model using COMSOL Multiphysics® software to compute Φ of TE materials without using conventional ZT parameters. The Φ were calculated using parametric programming in PDE by using special probe to capture change in power (∆P), ΔT, and area (A), thus (Φ = ∆P/A ... Read More

A rotational rheometer for Self-Consolidating Concrete was simulated as a yield-stress fluid in a 2D geometry. The effect of the vane geometry was investigated by comparing the analytical solutions with the numerical output for flow in the coaxial cylinders. This effect was studied by ... Read More

On transmission lines, the theft of redundant steel members from the transmission towers has been reported in recent years. The removal of these members from the tower can result in the collapse of the tower. An alternative to avoid this problematic is to replace some steel components ... Read More

The paper illustrates the use of COMSOL for obtaining the quantum mechanics wave function Ψ(x,y,z,t) as a solution to the time dependent Schrödinger equation. Once having Ψ(x,y,z,t), it can be used to compute the probability of a particle being in a specific zone within the spatial ... Read More

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... Read More

The primary motivation of this work was to develop flow models in porous media with fractal properties to represent the anomalous behavior observed in some pressure tests in naturally fractured reservoirs. Read More

Dielectrophoresis (DEP) is an electric field driven technique that has important applications in the enrichment, concentration and isolation of biological and non-biological particles. The assessment of particle trapping capacity using DEP, however, has been qualitative in nature; since ... Read More
