A Method for Evaluation of an Unsteady Preassure Field in a Mixed Potential-Vortical Domain Adjacent to a Rotating Wing

ABSTRACT

It is shown in the paper that a pressure field in a vorticity domain surrounding a rotating wing can be evaluated using the improved method of discrete vortices along with the Cauchy-Lagrange integral. The computational formulae are obtained for the cases of wing motion in either bounded or unbounded medium, and in either presence or absence of an external flow. Application of the method to the problems of rotation of a thin wing (vorticity generator) in an unbounded medium or near a screen indicates that the method provides a quite efficient and accurate way of evaluating the fields possessing high gradients of the pressure coefficient.
