Abstract
The dissipated effective energy in the refrigeration cycle can be recovered using the two phase flow ejector. Performance of the two phase nozzle plays an important role in developing the two phase flow ejector for the refrigeration cycle. It is important to know the efficiency of the two phase nozzles for refrigerant. The purpose of the present study is to elucidate the boiling phenomena in nozzle of the two phase flow of the refrigerant Isobutan. The experiment results shows that Isobutan have not so good boiling properties because the pressure distribution in nozzle don't much IHE model.
