Abstract:
Drag force calculation due to slip flows is important in predicting the performance of the microstructures with minimum feature size around 1 mm. In this paper, an efficient numerical approach to compute the drag force due to slip flows is presented. A 3-D numerical code was developed. The validation of this code was obtained by comparison of the numerical results in simple prototype flow, i.e. a sphere moving uniformly in an unbounded slip flow, with the asymptotic solution. Two different slip models were used in this study. A comparison of these two models is also given in this paper.
