Abstract :
The heat pipe applications have been coupled with the renewable energy sources such as solar energy, waste heat and geothermal energy. Thermosyphon Rankine Cycle (TRC) is a vertical wickless heat pipe engine. In this engine, the turbine is installed between the insulated section and a condenser section of thermosyphon. The mechanical energy developed by the turbine can be converted to electricity by direct coupling to an electrical generator. Our simulation results showed that the enhanced TRC model is able to increase the efficiency of the TRC system. This paper introduces the miscellanies new ways in order to improve the performance of a TRC system for supplying the sustainable electricity. For example, a0.78%increase in the turbine useful efficiency due to the superheating process was obtained.

كاربردهاي لوله ي گرمايي با انرژي هاي تجديدپذير نظير انرژي خورشيدي، گرماي هدر رونده و انرژي زمين گرمايي گره خورده است. چرخه ي را نكين ترموسيفوني (TRC) يك موتور لوله گرمايي قايم و بدون فتيله است. در اين موتور توربين بين قسمت هاي بي دررو و چگالنده ي ترموسيفون نصب ميشود.. انرژي مكانيكي بدست آمده از توربين كه مسقيما با ژنراتور برق درگير است؛ به الكتريسته تبديل مي شود. نتايج شبيه سازي كار حاضر نشان داد كه مدلي بهبود يافته از TRC قادر به افزايش دادن كارآيي سيستم TRC معمولي ميباشد. اين مقاله به معرفي راه هاي متنوع جديد به منظور بهبود دادن به كارآيي سيستم معمولي TRC براي تامين الكتريسته ي پايدار مي پردازد.. براي مثال درصد افزايشي كارآيي مفيد توربين در نتيجه ي فرايند فوق گرم كردن 78/0 درصد حاصل شد.
