Abstract

Decreasing the heat rejection of any power cycle is a promising agent in improving the overall performance and decreasing global warming. This can be done by different methods such as heat exchangers or thermosyphons.  Water is used as a working fluid.  The present experimental work used water as a working fluid and  investigated the effects of  filling ratio (27.2%≥Fr≥9%), total nozzle exit area to the turbine inlet area (4.3%≥Ar≥2.5%), and condenser cooling water flow rate (16LPM≥(V ̇) ̇≥8LPM). The results showed that the optimum-filling ratio is approximately 13.6% and the output power increases with increasing condenser cooling water flow rate. Also, the maximum output power produced at minimum area ratio but the optimum turbine rotational speed at area ratio of 3.1%.  In addition, the maximum output power without load from the present turbine is 5.28 W at Fr= 13.6 %, Ar=2.5% and V ̇=16 LPM
