WebTo test for curl, imagine that you immerse a small sphere into the fluid flow, and you fix the center of the sphere at some point so that the sphere cannot follow the fluid around. … WebNotice that we can tell how quickly a paddle wheel rotates by the magnitude of the curl, and we can tell whether each wheel rotates clockwise or counter-clockwise by the direction of the curl. This direction follows a "right-hand rule": if you curl your right hand so that your index finger through pinkie follows the flow of water around a point ...
