In this paper we present a lattice Boltzmann model to simulate compressible flows by introducing an attractive force. This scheme has two main advantages: one is to soften sound speed effectively, which greatly raises the Mach number (up to 5); another is its relative simple procedure. Simulations of the March cone and the comparison between theoretical expectations and simulations demonstrate that the scheme is effective in the simulation of compressible flows with high Mach numbers, which would create many new applications.
在本文中，我们提出了一种格子玻尔兹曼模型，通过引入吸引力来模拟可压缩流。该方案有两个主要优点：一是有效软化声速，这大大提高了马赫数（高达5）；另一个是其相对简单的过程。马赫锥的模拟以及理论预期与模拟之间的比较表明，该方案在模拟高马赫数可压缩流方面是有效的，这将创造许多新的应用。
