Abstract In the present communication, a performance investigation of a double-slope solar still augmented with parallel evacuated tubes under forced mode is carried out for a modified geometry. A comprehensive mathematical model is used for the numerical simulation using the experimental data and incorporating the effect of variable flowrate, water depth, and the number of tubes. An optimum flowrate range ∼0.006–0.007 kg/s/tube is found irrespective of the number of tubes and basin water depth to extract optimal energy. The flowrate is validated with other experiments, carried out by various authors. At optimal flowrate with ten tubes and 0.005 m basin water depth, the system yields 6.644 kg, while overall energetic and exergetic efficiencies are observed as ∼33.8% and 4.9%, respectively. With an increase in the tubes as 20 and 30, the respective yields are found to be increased by ∼2.64% and ∼6.62% for nearly the same collector output temperature attainable (≈98.5°C), while the energy and exergy efficiencies decreased significantly by ∼24.6% and ∼38.6%, compared with ten tubes arrangement. Daily yield and overall exergy efficiency are increased by 13.3% and 19.3%, respectively, using a diffused reflector.

Many experimental and numerical works have been done on different configurations of solar stills to optimize the design by investigative the effect of climatic, operational and design parameters on its performance. One of the most important of the operational parameters that has received a considerable attention in the literature is the brine depth. A study was subsequently conducted to verify this trend by an experimental investigation on three types of solar still that was fabricated with an area of 1 m2 and tested in the composite climate of Coimbatore, Tamilnadu, India, (Latitude: 11°N; Longitude; 77°E and an altitude of 409 m above sea level) with five different brine depths, namely 1, 4, 6, 8 and 10 cm. The present study clearly validated that the decreasing trend in productivity with the increase of brine depth.
