The Part 1 presented kinetic treatment of the slip flow and described kinetic flux vector splitting. The Part 2 of the paper presents the kinetic theory based approach for solving rotating slip flows. The paper describes numerical flow modeling of slip and rarefied flows. It also presents the meshless solver which makes use of least squares and Kinetic Flux Vector Splitting (KFVS) scheme and its Variance Reduction form (VRKFVS). The kinetic slip flow boundary condition is added with the Burnett terms which are quadratic in Knudsen number. The solver is able to capture slip flow features and typical features of the strongly rotating flows characterized by steep density gradient, supersonic flows, thin boundary layers towards the peripheral region with a rarefied central core.
