SIMPLE算法自1972年问世以来在世界各国计算流体力学及计算传热学界得到了广泛的应用，这种算法提出不久很快就成为计算不可压流场的主要方法，随后这一算法以及其后的各种改进方案成功的推广到可压缩流场计算中，已成为一种可以计算任何流速的流动的数值方法。-SIMPLE algorithm since its inception in 1972, countries in the world of computational fluid dynamics and computational heat transfer in academia has been widely used, this method quickly became the calculations presented the near incompressible flow the main method, then the algorithm and the subsequent to promote the success of various programs to improve the compressible flow calculation, has become a flow velocity can be calculated to any numerical method.
