前言沸腾是有相变的传热过程,可以用作为一种高强度的冷却方式。这过程广泛地应用于化工和食厂中的蒸发器,蒸汽锅炉,核反应堆与火箭中。特别是近几十年米,随着国民经济和尖端技术的发展,各种设备的表面热负荷也就越来越高,如大型锅炉可达5×10~5大卡/米~2时,喷气发动机10~8大卡/米~2时,而火箭燃烧室和核反应堆中竞可达10~(10)大卡/米~2时。 Introduction Boiling is a phase-change heat transfer process that can be used as a high-strength cooling method. This process is widely used in evaporators, steam boilers, nuclear reactors and rockets in chemical and food plants. Especially in recent decades, with the development of the national economy and cutting-edge technologies, the surface heat load of various equipment is also getting higher and higher. For example, when large boilers can reach 5 × 10 ~ 5 kcal / m ~ 2, Jet engine 10 ~ 8 kcal / m ~ 2, while the rocket combustion chamber and nuclear reactors up to 10 ~ (10) kcal / m ~ 2.
