ABSTRACT

Designers often need to find the shape of body that achieves specified design objectives. The classic problem of this type is to find the airfoil shape that leads to the desired distribution of surface pressure. This paper describes a method for solving such problems that is inexpensive, robust and a simple extension to existing CFD methods; it permits the body shape to be directly calculated by including the co-ordinates of the body as dependent variables in the problem formulation. The method described is applicable to many problems in thermo-fluids, but it is demonstrated here only for heat conduction problems.
