摘要
运用待定系数法 ,对Holly Preissmann格式进行了改进 ,补充了流速为负时的Holly Preissmann格式 ,并在此基础上建立了保守型对流方程的数值格式 .新建格式的计算结果与理论解吻合较好 ,且实用 .
Holly Preissmann scheme is improved and the scheme used for the minus velocity is added by use of the undetermined coefficient method. Based on the above, a new numerical scheme for the conservative convection equation is developed. Calculation results of the new scheme are found agreeable with the exact results. So the scheme is practical.
