Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... En savoir plus
In the early 1920’s, Gas-To-Liquids (GTL) and Coal-To-Liquids (CTL) technologies were developed to account for the depleting crude oil resources [1]. During this period, Franz Fischer and Hans Tropsch developed a process to convert synthesis gas (syn gas), derived from coal ... En savoir plus
Introduction Velocity profiles in liquid films flowing over rotating conical surfaces are of considerable interest in industry. The efficiency of important process equipment, such as spinning cone columns, fluid degassers, centrifugal disc atomizers, centrifugal film evaporators, and ... En savoir plus
H2SO4 is a very important chemical commodity, and indeed, a nation’s H2SO4 production has been a reasonably good indicator of its industrial strength for the last century or so1,2. Nearly 350 MM tons of H2SO4 was produced in 20143.The demand for H2SO4 in United States exceeds the supply ... En savoir plus
Chemicals are an integrated part of our daily life. While chemicals are significant contributor to a nation’s economy, sound management of chemical production is essential for environmentally friendly operation without maximizing operational costs. Next generation technologies must be ... En savoir plus
Customers typically prepare sandwiches using a microwave oven to heat a frozen sandwich. This causes huge temperature variations and quality issues due to multicomponent with different dielectric and physical properties and with phase changes at different freezing points in the heating ...

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With ... En savoir plus
INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus
Imaging of tissue with near-infrared diffuse optical tomography is emerging as a practical method to map hemoglobin concentrations within tissue for breast cancer detection and diagnosis. The accurate recovery of images by using numerical modeling requires an effective image ... En savoir plus
Droplet–based microfluidics has received special research attentions in last two decades due to its superior control over fluid flow as well as other unique advantages[1]. By introducing two immiscible fluids into microfluidic systems, the reagent fluid is encapsulated inside discrete ... En savoir plus
