二维Woods-Burnett方程的稳定性分析
Linearized stability analysis of two-dimensional Woods-Burnett equations
摘要
Abstract
The linearized stability analysis of two-dimensional Woods-Burnett equations was studied for the first time. The characteristic stability equation of this equation was first derived and the characteristic curve was achieved. The two-dimensional Woods-Burnett equations are not stable against small perturbations. The critical perturbation wave frequency is 0. 642 and the corresponding critical Knudsen number is 0. 130. This value is smaller than that of one-dimension equations, which is 0. 184. The two-dimensional Woods-Burnett equations are more unstable than one-dimensional Woods-Burnett equations.关键词
