Complex phenomena of two-phase flow occur during the phase change of refrigerant from liquid to vapour. To accurately predict the heat transfer and pressure drop, these flow phenomena should be incorporated in the design models for in-tube evaporators used in refrigeration and air- conditioning [1-2]. Traditionally, this is achieved by classifying two-phase flows into flow regimes and ...

MIE 1115S HEAT TRANSFER WITH PHASE CHANGE

In this course you will learn about the phenomena that control phase change of pure substances. Most of the course will be devoted to studying liquid-vapour phase change, with an emphasis on boiling. We will study the thermodynamics of phase change, vapour bubble nucleation and growth, heat transfer during boiling, and fluid mechanics during the flow of a liquid-vapour mixture. All students ...

After the occurrence of nucleation and condensation of vapour, a finely dispersed phase of liquid droplets has formed in the gaseous carder. Mostly, the droplets are so small that they can be considered stagnant with respect to the carrier gas, Further~ every change of state of the gas"vapour mixture will induce a partial change of phase in order to preserve equilibrium. The effect of phase ...
