摘要
用SIMPLEC算法计算了流动传热问题中2个有基准解的层流问题.对于2阶精度中心差分格式的2套网格数值解,用Richardson外推法可以得到4阶精度的解,其工作量比直接求解4阶离散方程的工作量减少许多;对于计算中的数值不确定度,用该方法分析了离散误差。
Two problems in laminar flow and heat transfer are evaluated by using the SIMPLEC algorithm. Fourth precision solution can be derived from two grid sets solution with a second precision central difference scheme by Richardson extrapolation. It reduces the amount of calculation. Uncertainty is determined from the discretization error analysis. A finer grid calculation is made to validate the extrapolation scheme.
