- 中文摘要: For convenience in engineering applications, we attempt to find a general regression relation between the nondimensional cavity length and the cavitation number for two-dimensional supercavitating hydrofoils. Based on observations of the general trend of the relation, a nonlinear function for these two physical quantities is proposed, and the coefficients in the function are optimally determined via a least-squares procedure and an iterative Gauss-Newton method. Several supercavitating hydrofoils, including flat-plate hydrofoils and hydrofoils with and without cambers, are investigated. The results seem to indicate that there exists a global approximate relation, the optimum coefficients of which depend on the flow conditions and hydrofoil shape.
