Abstract

The invention provides a fluid mixing testing device and method, and the device comprises a first fluid system which is used for providing a first fluid, controlling the preset parameters of the first fluid, and recovering the mixed fluid; the second fluid system is used for providing second fluid, controlling preset parameters of the second fluid and recycling the mixed fluid; the mixing system is connected with the first fluid system and the second fluid system and used for providing a preset mixing mode and a mixing space for the first fluid and the second fluid; the testing system is connected with the mixing system and is used for acquiring and processing temperature data of the fluid in the mixing space and the solid component placed in the mixing space; wherein the temperature of the first fluid is different from that of the second fluid. The method can objectively and effectively analyze the temperature fluctuation characteristics when fluids at different temperatures are mixed and the influence of the temperature fluctuation characteristics on solid parts.

Description

technical field [0001] The invention relates to the technical field of liquid mixing testing, in particular to a fluid mixing testing device and a testing method. Background technique [0002] Nuclear reactors operate by heating water (or other media) into steam to drive steam turbines to generate electricity through the large amount of heat energy generated by the nuclear fission process. The core, as a key core component, is composed of fuel assemblies and control rod assemblies placed in a core grid with a certain grid. Due to the special structure of the core assembly, the number of fuel assemblies distributed on the periphery of the control rod assembly is large and the distances are different, resulting in differences in the temperature of the coolant at the core outlet. The hot and cold fluids mix with each other in the form of jets and plumes, causing the temperature of the fluid in this area to change repeatedly, that is, thermal oscillations. The temperature fluc...
