Title Comparison between Navier-Stokes and DSMC calculations for low Reynolds number slip flow past a confined microsphere
Abstract In the present investigation, slip-continuum and molecular (DSMC) flow models have been used to compare the drag coefficient on a confined microsphere over a range of Knudsen numbers between 0.01 and 0.4. The simulations consider a fixed Reynolds number (Re=0.125) and a range of blockage ratios from 2.0 up to 13.0. Two separate problem formulations have been studied; the first considers flow past a confined sphere moving with a constant velocity along the central axis of the pipe while the second considers Poiseuille flow past a stationary confined sphere. Finally, their combination - the case of a confined sphere moving within the carrier Poiseuille flow is investigated using the DSMC method.
