“…By developing likely units, one can eliminate the use of a solar still, occupying a large space for operation and requiring more maintenance [5]. For a reference to previous work, Table 1 [7][8][9][10][11][12][13][14][15][16][17] shows some quality contribution by pioneers of the field. But none of them has made or developed such type of high distilled water unit at negligible cost.…”

India is presently focusing on complete utilization of solar energy and saving fossil fuels, which are limited. Various solar energy systems like solar cookers, solar water heaters, solar lanterns, solar PV lights, and solar lamps are continuously availing by the people of India at a low cost and on good subsidies. Apart from this, India is a solar energy promising country with a good number of solar homes (carrying solar energy systems) in its various locations. The present paper focuses on a unique combination of solar dish cooker (SDC) and solar water heater (SWH) to produce distilled water with a high distillate and a high daily productivity. The procedure has been discussed on the basis of experimental testing to produce distilled water by combining an evacuated type SWH and a SDC. Experimentation has been carried out in MIT, Moradabad (longitude, 28.83°N, and latitude, 78.78°E) by developing the same experimental setup on behalf of solar homes. The daily productivity of distilled water was found around 3.66 litres per day in full sunshine hours for an approximated pH value of 7.7 and a ppm value of 21. The payback period (PBP) has been estimated around 1.16 years of the present system.

“…The arrangement resulted in about 60% higher distillate output than the conventional solar still. To increase daily distilled water productivity of the conventional solar still Appadurai and Velmurugan [22] fabricated and tested an innovative design of solar still. Basin of the still was made with attachments like fins and coupled with a mini solar pond.…”

In the present study an attempt has been made to solve the problem of limited productivity of the conventional single slope horizontal basin solar still by improving its rate of evaporation. The conventional solar still is modified as a single slope inclined basin solar still with improved absorber surface. The absorber surface of the modified solar still is coated with black enamel paint and covered with copper chips. This resulted in augmented evaporation rate and in turn productivity of the system. The modified solar still having same footprint area as that of the conventional horizontal basin single slope solar still is fabricated and tested at Nagpur [21.14° N, 79.08° E] India. The effect of variation of feed water temperature (28°C-60°C) on the productivity of the solar still is also analysed. Theoretical modelling of both modified and conventional still is carried out and the results are compared. Experimentally the modified solar still is proved to be 9.5% more productive as compared with the conventional still. The details of modified solar still, experimental studies and the outcomes are discussed in the article.

“…They observed that taller cavity and central position of the fin give higher heat exchange. Appadurai and Velmurugan [10] used fins to improve the performances of a solar still. They conducted both theoretical and experimental work to compare conventional still and different types of finned stills.…”

In this study, heat transfer, flow structure and produced entropy due to natural convection in a threedimensional cavity heated via heat sinks are investigated numerically. One wall of the cavity is heated via pinfins and opposite wall is maintend at lower temperature. Remaining bouandaries are considered as adiabatic. Finite volume method is used to solve governing equations. Three geometrical cases are tested according to number and location of the fins. Other governing parameters are Rayleigh number and fin length. Number and length of the fins were found to be the most effective parameters on both heat transfer and entropy generation.
