摘要
综述了Navier-stokes方程的相似解,表明几乎所有已知的非线性相似解都可以通过伸缩变换的方法得到。论述了相似解所需要满足的条件：定常解下,速度或与坐标成正比或与坐标成反比；非定常解的存在,还依赖于某些特殊的时间关系。
Similarity solutions of the Navier-Stokes equations are reviewed. It is shown stretching leads to all existing significant nonlinear solutions. The steady state solutions proportional or proportional to distance. The unsteady solutions have a very specific time that the method of are either inversely dependence.
