Surrounding Fluid

Biomedical coatings are used to promote the wear resistance and the biocompatibility of a mechanical heart valve (MHV). An orbital shaking test was proposed to assess the durability of the coatings by the amount of eroded material due to the surrounding fluid. However, the shaker’s rotating conditions and the corresponding physiological condition was still lack of understanding. This study implemented numerical simulations by establishing a fluid dynamic model to evaluate the intensity of the shear stress under various rotating speed and diameter of the shaker. The results are valuable to conduct in vitro tests for estimating the performance of biomedical coatings under real hemodynamic conditions and can be applied to other fluid-contact implants.

We report here some preliminary results of 3–D numerical simulations of an α–ω dynamo in galaxies with differential rotation, small–scale turbulence, and a shock wave induced by a stellar density wave. We obtain the magnetic field from the standard dynamo equation, but include the spiral shock velocity field from a hydrodynamic simulation of the gas flow in a gravitational field with a spiral perturbation (Johns and Nelson, 1986).
