摘要:为了获得既能识别流动方向,又只用到最邻近的点的格式,推导了新的抛物线插值格式,并给出了两个算例来测试新格式在非正交网格上的性能。相比于中心格式(CDS),新的抛物线插值格式精度略高,收敛速度更快,且不易产生振荡。
A new parabola interpolation is constructed to obtain a better differencing scheme suitable for the arbitrary meshes. The new scheme is sensitive to flow direction and needs only the nearest neighbor nodes. Two cases were selected to test its performance on the non-orthogonal grids. Predicting results were compared with the results of other schemes and Peric's benchmark solution. In comparison with CDS, the new parabola interpolation demonstrates slightly more accuracy, faster convergence rate and less oscillation.
