Abstract : Two approximations to the linearized theory for supercavitating flow about slender bodies are applied to the case of flow past a slender wedge in a transverse gravity field. The additional lift and moment forces arising as a result of the gravity field are calculated by theories that are expected to hold when the gravity effects are of first-order smallness consistent with the linearization approximations. The lift and moment coefficients obtained from the two approximations are in general quantitative agreement over the most important cavitation number range. The results obtained confirm the validity of the average-value approximation introduced by Parkin. (Author)
