The need for freshwater grows by the day, yet the amount of freshwater accessible worldwide is insufficient to fulfil it. The distillation of saltwater could be a way to meet the demand for freshwater. The current study investigates the experimental performance enhancement of a tubular solar still (TSS) with various rotating wick materials. A rotating drum consisting of multiple wick materials (Black bamboo cotton fabric, jute cloth, terry cotton, and polyester) was placed within the tube to increase the evaporation rate. The basin water depth was set at 2 cm to increase the productivity of distillate water. The black bamboo cotton fabric wick outperformed the jute cloth wick, terry cotton wick, polyester wick, and conventional tubular solar still (CTSS) by 5.7 %, 12.44 %, 19.94 %, and 48 %, respectively, while maintaining the wicked drum speed around 1 rpm. Because of its moisture-wicking nature, the efficiency of a TSS with a rotating wick made of black bamboo cotton fabric is 50.65% greater than that of a CTSS. Compared to other wick materials, it had a high absorption and evaporation rate. Furthermore, the performance of TSS was investigated, using a black bamboo cotton fabric wicked drum at 0.3, 0.5, 1, 2, and 3 rpm. The studies indicated that a wicked drum speed of 0.5 rpm improves the productivity of approximately 7.474 Kg/m2. Furthermore, the average TSS efficiency was increased by 70.8 % compared to the CTSS.

Aluminium alloy hybrid composites are in high demand for advanced scientific applications due to their high strength, low weight, and enhanced tribological properties. A hybrid composite of aluminium alloy (Al7075) and aluminium oxide (Al2O3) and E-glass shot fibres was produced using a sand moulding technique in an electric resistance furnace. The objective of this research was to look at the wear characteristics of Al7075-Al2O3-E-glass hybrid composites with various Al2O3 (3-12%) and E-glass weight percentages (2-6 percent). The sliding distance (500, 1000, and 1500 m), load (10, 20, and 30N), Al2O3 (3, 6, and 9 %), and E-glass (2-6 %) are the wear characteristics that are considered. Wear testing is carried out using pin-on-disc equipment (WTE 165 model, Version-EV00) in line with the Taguchi L9 orthogonal array. Taguchi analysis was done on the collected data to find SN plots. Regression analysis was done along with ANOVA to find relationships between different factors selected. In order to reduce the wear rate of hybrid composites, the optimal wear parameters are determined. As the percentage of reinforcements increased, the rate of deterioration decreased. SEM scans revealed the attachment and displacement of unintended wear debris, as well as the uniform distribution of Al2O3/E-glass particles.
