On Methods for Analysis of Supercavitation in a High-Speed Motion in Water: Incompressible Approximation
ABSTRACT
The report presents results of development of approximate analysis methods and a review of possibilities to predict flow/motion processes which take place during a high-speed motion of bodies in water with a well-developed cavitation. Two characteristic velocity ranges are under consideration: moderate and ultra-high, the Mach numbers in water being M ∼ 0.5−2.5; each of the ranges corresponds to its field of applications and issues of the theory. The preferable approach is to analyze the problem as a whole on the basis of the simplest physical models. The consideration is based on a Matched Asymptotic Expansion Method in the approximation of a Slender Body Theory, in combination with other approximations and simple heuristic models, the analysis of dimensions and integral laws of conservation. The research uses the model of an ideal incompressible fluid. The covered problems include elongated, mainly axisymmetric, steady and unsteady cavities under a number of influences, and cavities with induced blowing.
