Summary

The model accounts for the thermal nonequilibrium vapour generation process along fully charged collector tubes. The local vapour generation rate is determined by solving the steady one-dimensional two-phase energy conservation equations in finite difference form along the flow path. Calculations have been made for a system fully charged by R11, with temperature-dependent thermophysical properties. The effect of solar insolation, for a controlled pressure system, on the vapour quality, and circulation rate is presented and discussed.
