| Research Abstract |
When the boundary has a sharp edge or a discontinuous temperature, the"slip boundary condition"cannot describe the correct behavior of the gas even when the mean free path of gas molecules is much shorter than the characteristic length of the system. In the present study, it is clarified how the slip boundary condition is modified in such cases, with the help of accurate numerical analysis based on a model Boltzmann equation and indirect theoretical approach based on the symmetry relations of the linearized Boltzmann equation.
