potential flow

• 1. 位势流: potential flow

• 1.位势流忽略(必需调整或者模拟)了重要的物理现象，如粘滞效应和断波现象。
  Potential flow codes omit (or have to be tuned to mimic) important physical phenomena such as viscous effects and breaking waves.

• 2.本文利用张量分析工具，对任意流面上的位势流，建立速度图方程，为解决一些特殊流动问题，提供一个分析方法。
  For potential flows on any stream surface, the equation of the velocity graph is set up by tensor analysis, and thus it provides an analytic method for solving some special flow problems.
