Numerical Modeling of Supercavitating Flows
Supercavitating bodies can achieve very high speeds under water by virtue of reduced drag: with proper design, a cavitation bubble is generated at the nose and skin friction drag is drastically reduced. Depending on the type of supercavitating vehicle under consideration, the overall drag coefficien...

| description | Supercavitating bodies can achieve very high speeds under water by virtue of reduced drag: with proper design, a cavitation bubble is generated at the nose and skin friction drag is drastically reduced. Depending on the type of supercavitating vehicle under consideration, the overall drag coefficient can be an order of magnitude less than that of a fully wetted vehicle. Slender-body theory and boundary element methods are two modern computational methods applied to the design of supercavitating vehicles. These course notes present recent advances in the theory behind these two computational approaches, as well as results and application of the methods to the simulation and control of supercavitating vehicles.
