Abstract

The invention discloses a high-temperature-resistant high-pressure-resistant visual rectangular narrow slot channel experiment device. The device comprises a conductive loop composed of an inlet conductive copper column, an inlet fixed electrode, a copper pigtail, a sliding electrode, a heating plate, an outlet fixed electrode and an outlet conductive copper column, a fluid flow channel composed of an inlet channel, an inlet buffer cavity, a rectangular narrow slot channel, an outlet buffer cavity and an outlet channel, a rectangular narrow slot channel which can bear high-temperature and high-pressure vapor-liquid two-phase fluid impact and is composed of a heating plate and quartz glass embedded in a groove of a ceramic matrix, a pressure measuring assembly embedded in the ceramic matrixand used for measuring relevant experimental parameters, and a thermocouple assembly. A fluid enters the rectangular narrow slot channel after passing through the inlet channel and the inlet buffer cavity; in the rectangular narrow slot channel, the fluid is boiled after being heated to form a vapor-liquid two-phase flow type structure; and bubble behaviors and flow type transition in the channelcan be effectively observed through the quartz glass, so that an experimental guarantee condition is provided for deeply researching flow and heat transfer mechanisms in the narrow channel.

Description

technical field

[0001] The invention belongs to a gas-liquid two-phase fluid visualization experiment device, in particular to a high-temperature and high-pressure visualization rectangular narrow slit channel experimental device, which satisfies the visualization research of two-phase bubble behavior and flow patterns in the rectangular narrow slit channel under high temperature and high pressure conditions. Background technique

[0002] Rectangular narrow slit flow channel is an important structural form of narrow slit channel. Due to the heat transfer technology of narrow slit channel, it has small heat transfer temperature difference, compact structure, no complicated surface processing and treatment, and can be replaced under the scouring of high-speed fluid in the channel. The hot surface is not prone to precipitation and pollution, and it has been paid more and more attention as a new heat transfer technology. It has been widely used in reactor engineering and other en...
