本文提出了一种无网格的数值方法来求解二维、无粘、不可压缩的小密度变化流动问题。该方法是涡方法的扩展，是基于离散化的涡流公式中写的方程。该方法进行了测试的精确解，并被发现是稳定和准确的。最后给出了二维线热源运动的一个应用。
We present a grid-free numerical method for solving two-dimensional, inviscid, incompressible flow problems with small density variations. The method, an extension of the vortex method, is based on a discretization of the equations written in the vorticity-stream formulation. The method is tested on an exact solution and is found to be both stable and accurate. An application to the motion of a two-dimensional line thermal is also presented.
