Abstract
A method is provided for determining an aerodynamic coefficient for a body immersed in a fluid under a set of fluid flow conditions. The method comprises obtaining surface flow parameter data for a plurality of locations on the body. These locations include body surface points straddling an area of the body surface where a leading edge stagnation point (LESP) is expected to be located. The method further comprises determining the LESP location and an angle of attack of the body with respect to freestream conditions of the fluid using the flow parameter data. The method also comprises determining the aerodynamic coefficient from the LESP location and the angle of attack using an aerodynamic model.
