Fig. 5From: A unified gas-kinetic scheme for micro flow simulation based on linearized kinetic equationThe steady solution of Poiseuille flow. Symbol shows the UGKS solution, comparing to the analytical solution and traditional discrete ordinate method solution. Left figure shows the solution with Knudsen number Kn=1.0, and right figure shows the solution with Knudsen number Kn=1.0×10−4Back to article page
