Line Integrals and Curl

Synopsis

Discusses the difference between rotational and irrotational flow. A float moving with the current in a tank of water may or may not rotate. Three flows are demonstrated: the first two both involve water flowing around circular tanks. But one flow is rotational,the other not. A mathematical test for rotational flow is derived. It is simply the ‘curl’ of flow down a long straight channel. The mathematics say it should by rotational, and experimentation shows it to be so.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
