PERFORMANCE ANALYSIS OF SOLAR THERMAL EVACUATED TUBE COLLECTOR USING DIFFERENT NANOFLUIDS

Energy use and energy security are greatly interrelated and corresponds to a major concern in the Indian energy sector. Renewable energy sector occupies an inevitable role in the sustainable development technologies in which the needs of the present generation are met without compromising the ability of the future generation to meet their own needs. Drastically increasing energy demand and environmental issues have motivated many international researchers for searching an alternative option to fulfill the future energy demand. In such a case, solar energy appears as the most attractive option due to its abundance and clean feature. Nowadays, solar thermal technologies are the most popular due to ease of application, high conversion factors and economic viability. The performance of solar thermal technology is dependent on certain factors such as nanofluids, solar radiation, collector tilt etc. The system efficiency depends on temperature of the different nanofluids used. Hence their performance analysis also holds greater importance in this context. In this paper, a performance analysis on the evacuated tube solar collector system with different nanofluids is being illustrated. The simulation of the same system is done with software named TRNSYS.
