In this paper, an effort has been made to evaluate the convective heat transfer coefficient and mass of water evaporated from a single slope passive solar still for different water depth (0.01, 0.015, 0.02 and 0.025 m) by various thermal models like Dunkle's model, Chen et al.'s model, Clark's model, Adhikari et al.'s model, Kumar and Tiwari's model, Zheng Hongfei et al.'s model and Tsilingiris model. These models were studied and compared with the experimental work. Also, the energy and exergy efficiency were calculated and the percentage deviation between experimental and theoretical prediction also listed out. The experimental validation of energy and exergy efficiency using different thermal models was carried out at Chennai, Tamil Nadu, India. By comparing the theoretical values of the hourly yield with the experimental data it was found that Dunkle's, Chen et al.'s model and Tsilingiris model gave better conformity between the forecasted and experimental results. Kumar and Tiwari's model yield is very high where as Clark's model, Adhikari et al.'s model and Zheng Hongfei et al.'s model predicts lower values as compared with the experimental results.

“…The exergy balance is analyzed for a water body, glass, and basin liner of both types of solar still on the basis of the first and second law of thermodynamics. 19 Exergy destruction happens in the components of the solar still due to the irreversibilities. As the heat capacity of the components of solar still is assumed to be negligible, the exergy accumulation in these components is neglected.…”

The paper presents an energy and exergetic analysis of simple and evacuated tubes solar still. Experimental analysis was carried out on a 1 m 2 basin area and a total of 18 evacuated tubes are attached to the lower side of the solar still. The results revealed that the highest exergetic efficiency of 70.8% and 34.6% was achieved in 0.03 m water depth passive and active solar still, respectively. The work is also focused on the evaluation of the exergy destruction in the basin liner, water, and the glass cover of the solar still. The maximum exergy destruction rate was found in the basin liner and the minimum is found in the glass cover for both simple and evacuated tube solar still for all water depths. The maximum exergy destruction of 3068 and 5129 W/m 2 was observed in the basin liner of 0.05 m water depth simple and evacuated tube solar still.
