一阶、二阶导数耦合的紧致差分格式及其应用
Derivation and application compact scheme of coupling of first and second derivative
摘要
Abstract
In the numerical calculation, the differential equations which are coupling equations of the first and second derivative need to be solved. In order to solve this kind of equations with the compact scheme, the compact scheme of coupling of the first and second derivative is derived. Using this scheme, the differential equations are dispersed directly. By the specific examples, the conclusions are that the compact scheme has advantages and is used to solve the two-dimensional partial differential equations.关键词
