摘　　要：通过试验研究管内工质流速、管壁热流密度对垂直下降流动受热管内过冷沸腾产生的影响，提出了垂直下降流动受热管内不发生过冷沸腾所应满足的条件，这对强制循环热水锅炉的设计和运行有一定的指导意义。An experimental study of subcooling boiling in a heated tube during vertically down flowing has been carried out. The influences of water velocity and heat fluxes in internal tube surface bave been checked. Based on the experiments, a criterion of subcooling boiling has been established, which is beneficial to the design and operation of forced circulating hot water boilers.
