Multhopp 网格在弯曲涡层计算中的超收敛性问题

The Superconvergence of Multhopp’s Discretizationin the Numerical Calculations for Curved Vortex Sheets

本文从理论上分析了Ｍｕｌｔｈｏｐｐ网格在弯曲涡面积分方程求解中的数值方法和超收敛性问题；并通过算例验证，证实Ｍｕｌｔｈｏｐｐ网格应用于弯曲涡层时，的确同样具有远大于其它任何网格计算的超收敛速度。

The nature of the superior convergence of the Multhopp’s discretization is theoretically analyzed for the numerical calculations of curved vortex sheets by the vortex lattice methods.In addition,numerical tests have been made to show that the superior convergence of the Multhopp’s discretization is indeed retained in the numerical calculations for th eurved vortex sheets.
