Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is described in further detail as follows:

[0016] Such as figure 1 As shown in the figure, build a horizontal and horizontal strip-shaped test pool 1, set up a wave blocking wall 2 and a wave dissipation wall 3 in the pool 1, and divide the pool 1 into a test area 4, a buffer zone 5 and a jet release area 6. An adjustable high-pressure water cannon 8 is set at the lower part of the end wall of the pool 1 in the test area 4 , and the axis of the jet 9 of the water cannon 8 is parallel to the radial direction of the pool 1 . Circular jet holes 10 with different diameters are set at the position where the axis of the jet 9 passes through the wave breaking wall 3 and the wave blocking wall 2 . The two ends and the bottom of the wave breaking wall 3 are provided with water passages, and the upper part is lower than the water surface 7 . The wave-stopping wall 2 is provided with water passages at both e...

Abstract

The invention provides a pressure wave water resistance test device with a homogeneous linear jet replacing a slender body, which is characterized in that incompressible water with no fixed form is used, rigidity with a surrounding water fluid is expressed in a high-speed jet, and the slender body is replaced to move at a high speed in the water fluid. In comparison with the prior art, the pressure wave water resistance test device with the homogeneous linear jet replacing the slender body has the advantages that the structure is simple, the application is convenient, the test cost is low, thedynamic pattern change low of a transverse pressure wave between the slender body in the high-speed movement of the water fluid and the surrounding water can be continuously expressed, and a vivid theoretical basis and parameters are provided for developing the high-speed slender body.

Description

[0001] 1. Technical field: [0002] The invention relates to the study of lateral pressure concentration resistance of a slender body in high-speed motion in an incompressible fluid, in particular to a pressure wave water resistance test device in which a homogeneous linear jet replaces a slender body. [0003] 2. Background technology: [0004] The law of movement of slender bodies in water fluids has always been a major topic of concern and research by major naval powers in modern times. It has become a hot topic in recent years. However, due to the effect of the gravitational field. The relationship between slender bodies, vacuoles and free liquid surface, the mechanism of interaction is very complicated. Also due to the instantaneous dynamics of the liquid waves of the head wave, the wake wave, and the pressure wave, there are major difficulties and numerous problems in its observation and research. [0005] 3. Contents of the invention: [0006] The purpose of the pres...
