Abstract:
In this paper, the organic fluid open Rankine cycle is analyzed when the variable expander is common assumption. The cycle arrangement in this plan is semi-open that is the layout is as a semi-cycle and the exhaust gas is directed to a drain tank. The effect of various parameters such as the inlet pressure on the expander, inlet temperature, pressure limit, injection rate on the thermal efficiency, the second law efficiency is measured and energy conversion to work is done with laboratory fixed effects. The highlighted characteristic in this study is the source serviceability capability in low-temperature and introduction of different blades as expander and its using to determine different organic fluids serviceability. This study shows that to what extent is the efficiency of the organic serviceable liquid R11, R22, R134a and how is each relation with the critical temperature and the impact of various changes on the cycle will be displayed and changes in temperature and flow rate, pressure and weights change will be analyzed and in the next stage expander replacement effect on results process will be shown. But what is important for us in this study project is to get work from lower temperature source, today’s using water is used as fluid as the main and original factor in powers with high costs to raise the water temperature to and using low temperature energy sources as the new energy for the future has importance and should be studied.
