The Effect of Inlet Water Mass Flow on a Double Glass Solar Still

Abstract

This article describes a new method for increasing the inlet water temperature of an inclined solar still by utilizing double glass heat condensation by increasing the inlet water temperature, thereby enabling the productivity of an inclined solar still. In a conventional inclined solar still, heat condensation is the energy that is wasted into the environment. This research method uses a combination of simulation and experiments in the laboratory. The simulation was based on the energy balance of the main components of a developed and conventional inclined solar still. The authors found that the water inlet temperature on a developed inclined solar still was affected by the inlet water flow. Our method improves productivity compared to the conventional inclined solar still maximum of 35.2% on the mass flow of inlet water of 3 l/hr. The new method of evaluation was confirmed by simulation and experiments on the variation of inlet water mass flow of 1, 1.5, 2, 2.5, and 3 l/ hr. The current study provides new research results that improve the productivity of an inclined solar still that can be used for purifying water with ease and simplicity, especially when purifying water in remote areas.
