摘要
建立了竖通道内自然对流换热的力平衡模型，阐述了热阻力和加热准则数的物理意义．分析了竖通道中自然对流的两个极限问题，即两种不同原因引起的阻塞现象；并将阻塞分为热阻塞和流动阻塞．提出了计算两种阻塞现象发生时的最大质量流量和散热量的计算方法．
model for the force balance of free convection in a vertical canal is developed Thephysical meaning of the thermal resistance and heating number are explained.The flowblocking and thermal blocking of free convection in the vertical canal are studied The maxi-mum rates of mass flow and heat flow during blocking are discussed and both types of blocking are verified by tests.
