Exposure to microgravity is known to alter genomic and proteomic expression and suppress immune cell activity. These changes may influence cancer development. Studying cancer cells in this environment, may help uncover novel therapeutic targets. SUNY Polytechnic Institute and SpacePharma, Inc. have teamed up to study the effect of microgravity on cancer cell migration. This will be achieved ...

We discuss the use of COMSOL Multiphysics 3.4 in the aerodynamic optimization process of the UNLV solarpowered UAV. We also address the use of COMSOL’s Multiphysics ability and how it was used within the scope of the project. In particular we highlight the development of wingtip devices, some of which are non-planar lifting surfaces, and we analyze how these changes affect the airframe ...

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation tool have been generated to two industrial problems using the ALE moving-mesh module in combination with the ...

Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the foaming process of a metal, we propose in this work a model which considers heat and mass transfer ...

Over the last years, the concrete technology has progressed in order to improve the quality of its use and mechanical performances. Despite the technical development known in the context of concrete, the esthetic aspect remains weakly treated. Among the esthetic problems, there is the formation and dispersion of air bubbles (Bugholes) inside the concrete during the concreting process. An ...

Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large differences in intra-pellet temperature were found in comparison with the average temperatures resulting from ...

In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical approaches and also with analytic estimations. Distributions of physical parameters over length and height of channel ...

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship . One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers . They developed from a desire for ‘fresh’ tea and the first ship to return with the new season’s tea could charge a higher ...

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. By introducing two immiscible fluids into microfluidic systems, the reagent fluid is encapsulated inside discrete droplets or slugs of nanoliter volume . Interestingly, two breakup modes, termed as “mono-dispersed” and ...

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the influence of a steady magnetic field on partial penetration keyhole laser beam welding of aluminum. Three-dimensional ...
