Holly-Preissmann格式的改进

Improvement of Holly-Preissmann scheme

  • 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。

     

    Abstract: 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.
