構造 H ハイドレートを作動媒体とする熱機関の熱効率

抄録

This paper reports the four phase equilibrium conditions and then analyzes thermal efficiency of heat engine using clathrate hydrate as the working medium. The working media was krypton and water plus each of the following substances: Neohexane and Methylcyclohexane. The heat engine was operated in the temperature range between 282 K and 293 K. Thermal efficiency was found to be 2.20% for the Kr hydrate, 2.35% for the Kr + Neohexane hydrate and 2.36 % for the Kr + Methylcyclohexane hydrate systems. The thermal efficiency was increased by 0.16 % when compared to a simple Kr system.
