The invention provides a multifunctional gas nuclei seeding device used for a pool. The multifunctional gas nuclei seeding device comprises an air compressor, a pressurization gas mixing tank, a control system and a nuclei seeding device. The air compressor is controlled by the control system. The nuclei seeding device comprises a main nuclei seeding device body installed at a false lifting bottom at the bottom of the pool and an auxiliary nuclei seeding device installed at the position of the lateral wall of the pool. The air compressor inflating the inner portion of the pressurization gas mixing tank in a pressurizing mode through a plurality of pipes distributed at different positions of the pressurization gas mixing tank, the pressurization gas mixing tank is connected with the main nuclei seeding device body and the auxiliary nuclei seeding device body through a pipeline, a valve, a flow meter and a water pump are arranged on the pipeline and a nuclei measuring instrument is arranged inside the pool. The multifunctional gas nuclei seeding device meets the requirement that under the test room conditions, the number of gas nuclei is the same in a unit volume, more accurate loads can be obtained in various taper ratio bubble experiments, and therefore the multifunctional gas nuclei seeding device can be applied to the fields of ship engineering and ocean engineering more widely.
Description
technical field [0001] The invention relates to a test device for ships and ocean engineering companies, specifically a multi-functional air-spreading nuclear device suitable for semi-open waters and adaptable to complex test conditions such as current making and wave making. Background technique [0002] Cavitation and cavitation phenomena widely exist in the field of ships and oceans. During the movement of propellers and high-speed planing boats, cavitation is the process of initiation, development and collapse of gas nuclei under the action of low-pressure fields. The initiation, development and collapse of cavitation are related to the number and scale of free gas nuclei in the water flow at the initial moment. [0003] In the field of shipbuilding and marine engineering, in order to ensure that the cavitation between the scaled model and the real object is similar in the scale test, the number of cavitation cells and the number of gas nuclei in the similar volume must ...
