地磁场中海水绕回转体流动诱导电场的数值计算

Electrical field induced by potential flow around axisymmetric body moving in unbounded conducting seawater through geomagnetic field

给出了描写地磁场中海水绕回转体流动诱导的电场的基本方程、边界条件及其计算方法 .在势流假定、忽略自由表面和海底影响的条件下 ,对绕兰金体 (Rankinebody)流场诱导的电场进行了数值计算 .

The governing equation, its boundary conditions and computing method for the electrical field induced by seawater flow around axis-symmetric body through geomagnetic field have been developed. On condition that irrotational flow has no free surface and sea bottom effects, electric field induced by flow around a Rankine body has been calculated.
