“…Experiments were carried out by changing the water depths from 1 to 5 cm under insulated and un-insulated conditions. The insulated double basin and non-insulated solar stills gave a higher production rate of 17.38% and 8.12% than the single basin still [14].Hansen et al developed an inclined type solar still which was experimentally studied using different wick materials on different absorber plate configurations. The new materials were selected for heat transfer co-efficient, water repellence, porosity, capillary rise, absorption to select a suitable material for the solar desalination application.…”

“…They proposed that the temperature difference between the cooling cover and water will improve the evaporation rate since large temperature differences are a driving force for the distillation process and will increase fresh water production. Increasing the evaporative area and/or condensing surfaces have been observed to enhance the performance of water distillation [9] and increasing the water temperature also leads to a greater production rate for distillation systems [10]. In the present study, mathematical calculations based on the phase-change phenomena are employed in a thermoelectric distillation system to identify and validate the fresh water and vapour production after one hour of system operation.…”

-In this study, mathematical calculations developed through water-vapour phase-change theory is used to interpret the processes involved in the fresh water production of a thermoelectric distillation system. The rate of water production depends on various parameters of vaporization phenomena such as water and vapour temperatures, pressure, specific volume, heat capacity and water-vapour surface area. The water-vapour surface area is constant 10 x 10 cm 2 , the initial depth of the sample water is 3 cm and the air occupies the 500 cm 3 volume inside the chamber. The volume and the mass of vapour and water at water-vapour interface are calculated through one hour of the system operation. The temperatures of the system components, humidity and water production of the thermoelectric distillation system are measured. As a result, an increase in the temperature of water and hot side of the thermoelectric module leads to an increase in the water production by increasing the vapour formation at atmospheric pressure. After one hour of system operation, the water production reaches 34.5 mL and the humidity inside the chamber increases from 51 % to 74 %. The results also show the distillation ratio is 11.5%. The mathematical calculations validate the experimental data with reasonable agreement.

“…Generally, the instant energy effectiveness of the solar still was calculated low throughout the day time. Elango et al [17] [19] has simulated heat and mass transfer singularities via finite difference technique to explain governing equations of solar still. He observed a close agreement among mathematical and investigational mass transfer information.…”

A B S T R A C TSolar still is a device, used to convert brackish water into distill water but the major issue low profitability and it is imperative to outline an ideal device. Computational Fluid Dynamics (CFD) simulation can help designers to improve the execution of a sun oriented still for a given cost. In this study, we examine the capacity of CFD simulation in calculation of heat and mass transfer in a single basin sun powered still. Experiments were performed in month of June in Jaipur, India. In this work, single basin solar still was fabricated and then optimized using CFD based methodology for water depth of 0.01m, 0.02m and 0.03 m. CFD based results help in a designing a solar still with maximum yield productivity of distilled water. It was concluded that maximum yield was achieved when water depth has minimum value i.e. 0.01 m. Total dissolved solid (TDS) value for sample water taken at water basin was in range of 500 PPM but after distillation water at output reaches below 50 PPM. Therefore, solar still was capable of improving the quality of water and brackish water of high TDS value can be reduced and used for drinking purpose.
