势流势流Potential flow势流(potential flow)势流是能由速度势确定的液流。与蠕变流不同，势流描述这样的条件:流动受惯性支配而粘滞力可以忽略。当一个流体的粘滞效应可以忽略时，大多数情况下.如果流体是从静止开始流动，则流体的流动始终是无旋的。对犷无旋流，存在一个速度势，速度矢量就是速度势的梯度。对J二不可压缩的液体·速度势满足拉普拉斯方程，这个方程在数学上已经得到了非常彻底的研究。对于可压缩的液流，势流以亚声速流动进行。对r流经一个很薄物体的跨声速流体，势流可以认为是很好的近似。然而.在超声速的流动中，强激波后面就不存在势流了。参阅“液流”(fluidfl(、w)、“流体流动原理”(fluid一fl()w pri:、eiples)、“流体动力学”(hydrodynamies)、“拉普拉斯无旋运动”(IJaptaee’5 irrotati〔)nal motion)、.‘势”(potentials)各条。势流满足不可压缩粘性流的纳维一斯托克斯方程，但是枯性流在固体墙上的边界条件不适用。因此，势流适用于许多低粘度流体的流动问题，如远离固体墙的空气和水，但是不适用于近墙壁的边界层流动。参阅“边界层流动”(boundary laye:flow)、“纳维一斯托克斯方程，，(Navier一Stokes equations)各条。〔佩(5 .1.Pai)撰〕
