TRANSIENT PERFORMANCE OF A HIGH-TEMPERATURE SOLAR DISTILLATION SYSTEM

The transient performance of a solar still coupled to a flat-plate sol ar collector and operating in the thermosiphon mode is presented. Perf ormance of the system has been evaluated considering the heat transfer coefficient as a function of the water temperature within the still. The effect of water depth on the performance of the proposed system is also addressed. The study reveals that it is worthwhile to consider a temperature dependent evaporative heat transfer coefficient when eval uating the performance of a high-temperature solar distillation system .
