摘要：
An experimental study is performed to investigate the critical heat nux (CHF) of wires in various thermodynamic states of FC-72. It is well known that the system temperature greatly affects nucleate boiling and CHF performance. When the system temperature is below saturation for a given system pressure, the thermodynamic state is either pure-subcooled or gas-saturated depending on the dissolved gas concentration within the liquid. The effects on CHF are investigated parametrically as a function of length scale, subcooling, and dissolved gas content. A single correlation accommodating these effects is suggested to predict CHF for small cylinders.
