Description

technical field [0001] The invention belongs to a gas discharge simulation device, in particular to a heat plume discharge simulation device of a power plant cooling tower in an environmental wind tunnel. Background technique [0002] With the development of my country's nuclear energy industry, the expansion of nuclear power construction from coastal areas to inland areas has been carried out in the industry one after another. Most inland nuclear power plant sites consider the use of natural draft cooling towers for secondary circulation heat dissipation. In order to realize the recycling of cooling water, tall natural draft cooling towers are often built to discharge waste heat into the air. Therefore, the cooling tower will cause a series of environmental problems, such as steam cloud shading, water mist falling, icing and so on. Compared with coastal nuclear power plant sites, the existence of tall cooling towers in the buildings of inland nuclear power plant sites incr...
