柯恩达效应（Coanda effect）是指射流附着在附近的表面上，即使该表面偏离初始射流方向，射流仍保持附着状态的现象。在自由环境中，射流离开喷嘴时会夹带并与周围环境混合。当一个表面靠近射流时，这就限制了该区域的卷吸。当流动加速以试图平衡动量传递时，产生穿过射流的压力差，并且射流被偏转以更接近表面，最终附着到表面。
Coanda effect is the phenomena in which a jet flow attaches itself to a nearby surface and remains attached even when the surface curves away from the initial jet direction.In free surroundings, a jet of fluid entrains and mixes with its surroundings as it flows away from a nozzle. When a surface is brought close to the jet, this restricts the entrainment in that region. As flow accelerates to try balance the momentum transfer, a pressure difference across the jet results and the jet is deflected closer to the surface eventually attaching to it.
