A solar still is used to convert saline water into potable water by means of the distillation process. In order to improve the productivity of conventional solar still, various modifications are implemented by researchers. In the present study, multiple V-shaped floating wicks are used to enhance heat absorption and thereby increase productivity. The experiments are performed during the summer and winter seasons in Rewa, India (Latitude: 24.5373° N; Longitude: 81.3042° E). These multiple floating wicks are made from black jute cloth wrapped in V-shaped pieces of thermocol. Because of their V-shaped profile, the evaporative surface area of modified solar still is 26% larger than that of conventional solar still. The maximum daily productivity in one of the clear days is found to be approximately 6.20 kg/m 2 in summer and 3.23 kg/m 2 in winter with daily efficiencies of 56.62% and 47.75%, respectively. A theoretical thermal model is formulated by using the energy balance equations of the modified solar still. Reasonable agreement was seen between the theoretical and experimental results of modified solar still. An economic analysis is also performed for the modified solar still and conventional solar still; in a 10-year life cycle, the annual cost of distilled water is estimated at Rs. 1.81/kg for the former and Rs. 2.24/kg for the latter.

“…Comparison of present work with reported designs with respect to distillate output, still efficiency and cost of the still is presented in Table 4. Distillate output for the still depends on the climatic conditions and varies from place to place, however the still efficiency can be used to compare the performance of various stills form different places [23]. The present work has higher distillate output and low cost than most of the reported still designs.…”

Effect of the orientation on the yield of the stills has been discussed in this experimental work. Two identical modified stills S1 and S2 fabricated, each with 0.5 m 2 of basin area. Stills had transparent glass walls with trough to collect the condensate from the walls. Mixture of highly porous coco peat and charcoal were used as basin material. Still S1 had North-South (N-S) orientation with cover slope due south whereas still S2 had East-West (E-W) orientation with cover slope due east. Experiments were conducted by changing the water quantity in the solar stills ranging from 5 to 10 kg. Maximum distillate output of 5.67 L/m 2-d was obtained for S1, whereas it was 5.45 L/m 2-d for S2 for an average solar radiation intensity of 695 W/m 2 (25 MJ/m 2-d). The increase in the yield of S1 over S2 due to the orientation was found to be in the range of 0% to 11%.Use of transparent walls increased the condenser area by 78.4%.The distillate water cost per litre was estimated as Rs. 0.86 (0.013 US$) and Rs.0.90 (0.014 US$) for S1 and S2 respectively. Energy payback time (EPT) for stills S1 and S2 was estimated as 4 months.

The joint for two different materials (AA5052 and AA6061) can be done by the Dissimilar Friction Stir Welding (DFSW) process. Therefore, this study was conducted to analyze the mechanical properties of dissimilar welding joints. In this study the DFSW process uses a tool with a shoulder Ø 17.8 mm and a cylindrical pin Ø 5 mm. FSW blocking is done on conventional milling machines with 1300 rpm, 1950 rpm and 2850 rpm tool rotation variations, while the welding speed variations are 43 mm / min, 130 mm / min and 240 mm / min. The results of mechanical properties testing showed the highest hardness value obtained was 55.3 HBN at 1300 rpm with 240 mm / min feeding, the highest tensile strength occurred for 1300 rpm and 240 mm / min feeding at 123.51 MPa. The fracture of the tensile test results generally occurs in the HAZ area and the AA5052 base metal Nugget. Investigation results show that the DFSW connection of aluminum alloy material AA 6061 and AA 5052 adapt is well connected, but in terms of general strength the tensile strength of the joint (HAZ and Nugget) is smaller than the tensile strength of the base metal. This DFSW connection adaptation is applied to connections that do not accept load or tensile strength due to the load received by the connection not to exceed the maximum tensile strength of base metal AA 5052
