Sedimentation of a circular disk in power law fluids

The continuity and momentum equations have been solved numerically for the two-dimensional steady flow of power law fluids over a thin circular disk oriented normal to the direction of flow. Extensive results on the individual and total drag coefficients are obtained as functions of the power law flow behavior index (0.4 < or = n < or = 1.0), Reynolds number (1 < or = Re < or = 100) and the blockage ratio, disk-to-cylinder diameter ratio (0.02 < or = e < or = 0.5), which can be used to estimate the settling velocity of a circular disk. The numerical predictions of drag are consistent with the scant experimental results available in the literature.     

Numerical simulation of convective diffusion at a microarray channel electrode

Concentration profiles and currents were simulated for an array electrode on one wall of a rectangular flow-throuh channel, using the backward implicit finite difference numerical procedure to solve the equation governing the convective diffusion process. Different simplifying hypotheses usually considered in these types of calculations, and their concomitant errors were analyzed. A simple criterion for estimating the importance of longitudinal and lateral diffusion was developed. The responses of a variety of both regular and pseudo-randomly distributed geometries of array electrodes were evaluated under a wide range of conditions. Current response was evaluated as a function of the number of active sites, fractional surface blockage, and flow conditions, relative to solid electrodes. The geometrical pattern of the array was found to affect the current response, a regularly spaced array yielding the maximum response for a given degree of partial blockage of the electrode and a constant number of microelectrodes.
