Numerical and experimental research on hybrid temperature diffusion for four pairs of symmetric sources and sinks
摘要：
采用模型实验和数值模拟相结合的方法，研究了不同通风量下不同温度和流量的热射流的温度扩散规律。提出了适用于评价通风方式对控制区域内最高温度的影响的指标——基于热源的温度效率，并探讨了复合温度扩散反问题。

Abstract：
Using the method of model experiment combined with numerical simulation, studies temperature diffusion characteristics of heat jets with different temperature and flow rate under different ventilation rates. Proposes an evaluation index for the effect of a ventilation mode on controlling the highest temperature in a zone, i.e. the temperature effectiveness based on the heat source. Discusses the inverse problem of hybrid temperature diffusion.
