强制对流是对流的一种，是指由外力（如风扇、泵、吸力等）驱动的流体运动。强制对流可以有效的交换大量的热量，是一种常见而有效的热交换方式。

一般生活常用到强制对流，像是中央供暖、空气调节、蒸汽涡轮发动机等。而当一个人冲着食物吹气以降温时，就使用的也是强制对流。工程师在设计或分析热交换器、管流、或是流体流过一片和流体温度不同的平板（像太空船机翼在再进入地球时）等，都会用到强制对流。

Forced convection is a mechanism, or type of transport in which fluid motion is generated by an external source (like a pump, fan, suction device, etc.). It should be considered as one of the main methods of useful heat transfer as significant amounts of heat energy can be transported very efficiently.
