摘要: 采用能量估计和Helmholtz分解方法证明了在二、 三维空间上, 当马赫数趋于零时, 可压缩燃烧方程解的极限收敛到不可压缩燃烧方程的解.

关键词: 燃烧方程, 可压缩, 不可压缩, 马赫数

Abstract: The aim of this paper is to prove that compressible combustion flow in two- and three-spaces dimension converges to the incompres sible flow in the limit as the Mach number tends to zero. The proof relies on energy estimate and Helmholtz decomposition.

Key words: combustion flow, compressible, incompressible, Mach number
