Lift coefficients on a supercavitating jetflapped foil between rigid walls
Abstract
The method of matched asymptotic expansions is applied to the firstorder theory on the flow past a twodimensional supercavitating jetflapped foil in a wall tunnel, and a solution (the slope of the jet) of the governing integrodifferential equation is obtained and represented as the series expansion in ascending powers of delta and log delta multiplied by functions of the distance from the trailing edge, where delta is a small perturbation quantity proportional to the jet momentum coefficient. Moreover, the lift derivatives with respect to incidence and jet deflection are obtained as the series expansions in ascending powers of delta and log delta.
