Applied hydromechanics, Vol. 5 (77) ¹ 1, (2003) |
| Distribution of static pressure on the surface of a body of revolution has been measured experimentally, as well as full and static pressure in a cross section of a nozzle, at varied suction. On the basis of the integral Karman equation, influence of suction amount and the shape of rear part on hydrodynamic drag of the body has been estimated. Has been proposed a method of hydrodynamic drag reduction of water when a body of revolution moves in viscous fluid, that allows for essential reduction of momentum loss for account of boundary-layer interaction, fluid extraction and the shape of rear part, and its implementation. |
