Thermal conductance associated with Couette flows as a function of the Knudsen number. The conductance is normalized by the continuum value k /d.
Grahic Jump Location
Comparison between the viscous heating rates obtained from the direct simulation Monte Carlo simulation and from the analytic solutions. The continuum solutions incorporating the slip boundary conditions give qvisc/2=μV2d/2(d+2λ)2, where μ is the viscosity of air.
