Abstract
The Couette flow of a rarefied gas between two concentric cylinders is analyzed numerically for an inverse Knudsen number ranging from 0 to 10 and different gap‐to‐radius ratios. The model of the Boltzmann equation proposed by Bhatnagar, Gross, and Krook is linearized and the transport integro‐differential equation reduced to a purely integral one, which is solved numerically. The resulting drag coefficients for the outer cylinder are in a good agreement with available experimental data.Keywords
