请教附壁效应的物理原理
|
|
不知道这个发到哪个版合适。 工作中遇到一台粉末分级设备,是基于附壁效应(或者coanda effect)的原理设计的,网上查了查,有很多相关视频,但是没找到相关机理的介绍,想了解一下,产生附壁效应的机理是什么,是什么力使流体吸附于固体表面,谢谢。 |

The Coandă effect is a result of entrainment of ambient fluid around the fluid jet. When a nearby wall does not allow the surrounding fluid to be pulled inwards towards the jet (i.e. to be entrained), the jet moves towards the wall instead. The fluid of the jet and the surrounding fluid should be essentially the same substance (a gas jet into a body of gas or a liquid jet into a body of liquid). In one application, a jet of air is blown over the upper surface of an airfoil, which can have a strong influence on the overall lift, especially at high angles of attack when the flow would otherwise separate (stall). See Blown flap. http://en.wikipedia.org/wiki/Coand%C4%83_effect |
