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 ... Mehr lesen
Rick has a BS in Physics, a ScM in Geological Sciences, and a PhD in Physics. He worked at Air Force Geophysics Laboratory, Conoco Petroleum Exploration Research, and, since 1989, has been at the DuPont Experimental Station. In this industrial setting, Rick has had opportunity to work on ... Mehr lesen
Sound vibrations are collected from the external environment by the eardrum and are guided to the basilar membrane in the cochlea. Pressure differences in the two scalae of the cochlea result in a traveling wave on the basilar membrane. The tiny displacements are detected by the ... Mehr lesen
Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing ... Mehr lesen
According to clinical reports, cardiovascular disease has become a major global healthcare problem. The deposition of fats, cholesterol etc. at the arterials walls causes thrombus formation leading to stenosis and arterial blockage. To tackle this, along with arterial bypass, the use of ...

The elastic and geometrical properties of Low Density Polyethylene (LDPE) foam are used in this paper to improve the attenuation properties of periodic arrangements of acoustic scatterers known as Sonic Crystals (SCs). A specific recycled profile of LDPE foam is used as elastic-acoustic ... Mehr lesen
The analysis of an impinging jet in a cross-flow and the resulting vortical structures are presented. A computational fluid dynamics simulation utilizing the k-ε model for turbulence is validated in COMSOL Multiphysics® by comparing the results to previous experimental and theoretical ... Mehr lesen
Ruptured aortic aneurysm is one of the commonest cause of mortality in developed countries. To avoid it interventional repair is an effective treatment. In the recent years the development of new therapies, such as stent implantations, allows to perform this treatment more and more ... Mehr lesen
Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then ...
