求解动力学边值问题的新方法

New method of solving of boundary problems in kinetic theory

A. V. Latyshev, A. A. Yushkanov

摘要:

考虑了动力学理论中具有镜面-扩散边界条件的经典Kramers问题。本文以Kramers问题为例,提出了判定动力学边值问题的新方法。该方法允许以任何准确度接收决策。在方法的基础上,提出了在动力学方程中以源的形式表示分布函数上的边界条件的思想。利用Furier积分将含源动力学方程化为第二类Fredholm型积分方程。这个决定是以诺依曼级数的形式得到的。

英文摘要:

The classical Kramers problem with specular -- diffuse boundary conditions of the kinetic theory is considered. On an example of Kramers problem the new method of the decision of the boundary problems of the kinetic theory is stated. The method allows to receive the decision with any degree of accuracy. At the basis of a method lays the idea of representation of a boundary condition on distribution function in the form of a source in the kinetic equation. By means of integrals Furier the kinetic equation with a source is reduced to the integral equation of Fredholm type of the second kind. The decision is received in the form of Neumann's series.
