Shot-film flow liquid metal free surface system

Abstract

The invention specifically relates to a jet-film flow liquid metal free surface system. It includes a jet generator, a jet nozzle and a jet-film flow bottom plate. The jet generator is a metal cavity. A liquid metal inlet port is provided on one side of the jet generator, and a jet nozzle is provided on the opposite side. The jet generator The bottom side of the jet-film flow base plate is connected, and the jet nozzle is located above the jet-film flow base plate. With this system, by properly adjusting the diameter and arrangement of the jet nozzles and the angle with the jet-film flow bottom plate, a stable and smooth jet-film flow can be obtained.

Description

Shot-film flow liquid metal free surface system technical field The present invention relates to the liquid metal free surface system for tokamak fusion device, be specifically related to a kind of Shot-film flow liquid metal free surface system. Background technique The first wall hanging tile, divertor and limiter of tokamak fusion device are key components of fusion device, requiring it They have high thermal conductivity, low sputtering, and resistance to neutron radiation, that is, the ability to withstand high thermal loads and high neutron fluxes. However, solid-state surfaces It is difficult to meet the high heat load of more than 20 megawatts per square meter, and at the same time, various performances will degrade after neutron irradiation. Therefore, the free surface of liquid metal can bear the surface thermal power density of more than 50 megawatts per square meter, and it is easy to Through the advantages of cyclic renewal and life limitation without ...
