Applied hydromechanics, Vol. 4 (76) ¹ 2, (2002) |
| The results of development of the approximate calculations methods and analysis of possibilities of flow and motion prediction apply to bodies high speed motion in water are presented. Two characterize ranges of the speed: moderate and super high speeds for Mach Numbers in the water M~0.5-2.5, are considered where different applications and developed parts of the theory correspond every of this ranges. Preference are gave to the consideration on base of the simple physical models. Consideration is based on the "Matched Asymptotic Expansion Method" in approximation of the "Slender Body Theory" together also with another approximations and simple heuristic models with application of the dimension analysis and integral conservation laws. Investigations of the part I are based on ideal incompressible fluid model. The problems of the calculations of the prolate mainly axisymmetric steady and unsteady cavities with account of number of the factors and unsteady cavities with gas injection are considered and analyzed. |
