摘要：
Understanding CHF is of an upmost importance in many industries, especially in the design and operation of boilers, nuclear power plants. cryogenic systems. etc. Due to safety issues related to the nuclear power plants, and the adaptation of CHF as the limiting criterion of power generation, it is important to understand the mechanisms of CHF relevant to nuclear systems operation. Moreover, CHF is expected to occur during transients than steady-state conditions Therefore. knowledge of transient CHF is of great importance for the safety evaluation of nuclear reactors under transient condition. In this paper, the existing CHF experimental and modeling studies are discussed in order to understand the phenomena leading to CHF Also, the effect of transient conditions on CHF for nuclear fuels has been evaluated.
