A moving-boundary formulation for modelling time-dependent two-phase flows.

Author(s) : GRALD E. W., MACARTHUR J. W.

Type of article: Article

Summary

A mathematical model describing the transient interactions in one-dimensional two-phase flows with heat transfer is presented. A moving-boundary refrigerant model is used to predict the position of the two-phase/vapour interface. A boundary immobilization is used to predict the temperature profile along the heat-exchanger wall. Typical results of an evaporator model, in terms of interface position and discharge superheat, are presented for inlet flow disturbances. The model is used in an overall heat pump simulation to predict cyclic performance.
