Model experiment device for saline water doing horizontal jet movement under action of heat plume

Abstract

The invention discloses a model experiment device for saline water doing horizontal jet movement under action of heat plume. The model experiment device comprises a main water tank, a jet saline water system, a plume saline water system, a flow field testing system and a pipeline, wherein the jet saline water system comprises a jet saline water tank, a jet water supply pump, a jet constant-pressure water tank, a jet paint box, a jet floater flow meter, a jet water distributing tank and a jet injecting port; the plume saline water system comprises a plume saline water tank, a plume water supply pump, a plume constant-pressure water tank, a plume paint box, a plume floater flow meter, a plume water distributing tank and a plume injecting port; the jet constant-pressure water tank is communicated with the jet paint box by a water pipe; and the plume constant-pressure water tank is communicated with the plume paint box by a water pipe. The model experiment device can be used for basic application research on indoor airflow organization so as to overcome the defects of inaccurate calculation of a current air distribution jet formula, low credibility of CFD (Computational Fluid Dynamics) numerical simulation, high cost of air model experiment and difficult realization of visualization and the like.

Description

technical field [0001] The invention belongs to the technical field of experimental research, and relates to a model experiment device, in particular to a salt water model experiment device for horizontal jet movement under the action of a heated plume. Background technique [0002] With the rapid development of the economy and society, the level of construction technology and the improvement of people's living standards, more and more tall and large space buildings have become residential spaces for people to work and live, such as concert halls, cinemas, stadiums, factories, transportation hubs, etc. The design of air-conditioning air distribution in tall and large-space buildings has always been a technical difficulty, especially in large-space layered air-conditioning environments. At present, large-space buildings generally adopt the layered air-conditioning method with horizontal and side-flowing nozzles to achieve the purpose of ensuring that the work area meets the a...
