Abstract
In recent years the surface source method of potential flow about arbitrary bodies has been developed extensively and has proved to be a useful tool. Refinements have been made to the basic method to improve computational speed and accuracy by using higher order representations. Although large increases in speed and accuracy have been achieved, so far no technique has been developed that will enable the body to be modified and changes in the flow characteristics to be calculated. This paper describes the use of B-splines in the surface source method where changes in the flow characteristics can be investigated by modifying the input curve. Sample results are given to show the accuracy of the method.
