摘要
本文提出了一种适于绕流问题的数值方法,它考虑了流场中不同区域内不同的物理现象,给出了外部边界条件的良好逼近。使用这种方法可以节省大量的计算机存贮单元和计算时间,也可以推广到三维绕流问题的数值计算。
A numerical Method for the outer flow problem is proposed in this paper, which considers the different physical phenomena in different regions in the flow feild and gives a good approximation for the outer boundary condition. This method can save a lot of memories of computer, takes less computational time and can easily be used for the numerical calculations of the three-dimension outer flow.
