- 将一种高效的数值计算方法——多重网格法引入储油罐内静电位的计算。作为实例, 对一圆柱形储油罐内的静电位分别采用解析法、超松弛、多重网格法进行了计算。结果表明, 多重网格法, 特别是完全多重网格法, 极大地提高了计算速度, 为储罐内的静电位计算提供了一种高效的计算方法。
Multi-grid method(MG), a highly efficient numerical algorithm, is introduced to solve the electrostatic potential distribution in a cylindrical tank. As an example, the potential in a cylindrical tank is calculated with analytical method, successive over- relaxation algorithni(SOR) and MG algorithm respectively. Results Show that MG algorithm, particularly full multi-grid algorithm (FMG), can considerably increase computation speed. So it provides a highly efficient method for calculating the electrostatic potential in acylindrical tank.2007,06(06): 1-5 收稿日期：2006-10-18分类号：TE972.1作者简介：王菊芬(1975-), 女, 浙江温岭人, 工程师, 2006年毕业于重庆后勤工程学院油气储运工程专业, 博士, 主要研究方向为油流流动带电现象.参考文献：
