高大厂房热风供暖气流组织实验研究

Experiment of air distribution in a hot air heated tall workshop

利用模型研究了热风供暖系统的气流组织，分析了实验范围内圆形风口等温与非等温射流轴心速度的衰减，找出了射流流量、热气流上飘、热射流上下两部分流量的变化规律。

Presents a model experiment of air distribution of hot air heating, analyses the axial velocity decay of isothermal and non isothermal jets from a circular nozzle, finds out the change pattern of jet volume, warm jet lift due to buoyancy, volume ratio of the upper and lower halves of the jet, and recommends the results to be referred in design of hot air heating in tall workshops.
