Fig. 6From: A unified gas-kinetic scheme for micro flow simulation based on linearized kinetic equationCouette flow velocity profile in the upper half channel with Knudsen number \(\text {Kn}_{s}=0.2/\sqrt {\pi }\), \(\text {Kn}_{m}=2/\sqrt {\pi }\), \(\text {Kn}_{l}=20/\sqrt {\pi }\). UGKS solution is shown in symbol, the linear Boltzmann solution is shown in solid line, and the NS solution with slip boundary condition is shown in dashed lineBack to article page
