沸腾传热中的非平衡性非线性特性研究

A series of investigations was conducted to recognize and understand nucleation site interaction phenomena and bubble dynamic behavior. The non-equilibrium interaction between wall, liquid and thermal process was analyized and associated new heat transfer expressions were derived. A cluster model of nucleation was proposed to describe physical structure of nucleation and bubble evolution and scale effect was recognized. Jet-flow and bubble sweeping were observed on a very small heating wire. These phenomena reveal that there exist highly non-equilibrium and non-linear interaction in boiling and provide new evidences for understanding complicated phenomena.
