Hydrodynamic performance of underwater lift surfaces in high-speed navigation.
The optimal solver for hydrodynamic investigation of waterborne lift surfaces.
Using Navier-Stokes-based CFD simulations, two standard problems were studied, and the hydrodynamics of submerged lift surfaces were investigated. (1) Flow around a three-dimensional submerged lift surface with an elliptical shape and a constant camber wing cross-section. (2) Flow around a two-dimensional symmetric wing cross-section. The dependence of the resulting hydrodynamic loads on changes in velocity and angle of attack was examined under fully submerged conditions that allowed for the occurrence of cavitation. A comparison of results obtained from numerical simulations and measurements from experiments conducted in a pressurized test tank facility was presented.
