Abstract

The invention provides a device for generating water vapor at constant temperature and back-injecting same-temperature water and relates to the field of cavitation and super-cavitation. A middle partition is arranged inside a box to divide the same into an upper portion and a lower portion, and the upper portion of the box and the lower portion of the box are in one-way communication; through action of a vacuum pump, pressure intensity of the upper portion of the box can be changed, so that pressure intensity of the lower portion in one-way communication with the upper portion of the box can be changed; when the pressure intensity of the lower portion of the box is lower than saturated steam pressure of water, water stored in the lower portion of the box can be gasified to form water vapor which enters the upper portion of the box; when the upper portion of the box is filled with water vapor, a first through hole is closed, and an air injection pipe height adjusting rod is separated from an air injection pipe to realize communication between the upper portion of the box and the lower portion of the box through the hollow air injection pipe; air is injected into an airbag through a compressor, water vapor in the upper portion of the box is back-injected into water identical with water vapor in temperature through the hollow air injection pipe.

Description

technical field [0001] The invention relates to the technical field of fluid cavitation and supercavitation, in particular to a device for generating water vapor at a constant temperature and injecting water at the same temperature back. Background technique [0002] Cavitation generally occurs in fluids. Specifically, cavitation generally occurs at the solid-liquid interface. When the pressure in a local area is lower than the saturated vapor pressure of the liquid, a cavity will be formed. Bubbles) will no longer be liquid but be filled with steam or air (it is currently believed that the interior of the cavity is mainly steam). According to the shape and size of the formed cavitation, the cavitation formed by cavitation can be divided into different types such as migratory cavitation, sheet cavitation, cloud cavitation, and supercavitation. Regardless of any kind of cavitation, the formation mechanism of the cavitation, the movement shape and the collapse mechanism of th...
