与普通民用建筑不同，工业厂房（车间）往往会产生大量的热负荷（其热强度可达50-300W/m3）。如何因势利导、充分利用热源的羽流效应诱导实现合理、高效、有组织的热压自然通风气流组织方式、改善生产及工作环境，是一项具有重要工程意义的课题。 本研究旨在通过理论解析、CFD模拟，实验室测试和典型工业厂房现场测试：. (1) 查明工业热源自由及受限热羽流扩散基本模式的流动与换热过程；. (2) 建立当量组合热源模式、无因次热分层高度特征参量及表达式；. (3) 提出工业厂房（热车间）当量组合热源模式的排风温度及通风量设计计算方法； . (4) 推荐高大工业厂房（热车间）有组织热压自然通风合理设计方法。促进我国暖通行业的技术进步。

Project title：Thermal-driven natural ventilation design process for industrial workshops based on the equilent composite heat sources and strification heights Remarkably different from general civil constructions, a large amount of heat is released in the large industrial workshops during the production process. The heat intensity can reach as much as 50-300W/m3. For this kind of plants, natural ventilation thermal-driven is high economic ventilation with high air removal efficiency. With theoretical analysis, CFD simulation, field test of the typical plant workshops, it aims to ： (1)identify the characteristics of the air flow and heat transfer, which is induced by the free and the confined thermal plume from the typical heat source; (2)propose the characteristic parameters to express the dimensionless thermal stratification height and equilent composite heat sources; (3) reveal the thermal plume mechanism with equilent composite heat sources and find out the reasonable calculation method of exhaust temperature and air exchange rates ; (4) based on the thermal stratification height and the combination heat source mode, recommend the efficient design method of natural ventilation for the large industrial plants workshops. This research will promote the technology progress of the HVAC field in China.
