Mathematical Modelling of Single Slope Solar Still with Ambient Temperature and Global Irradiance

Abstract

This work models a single slope solar still. The ordinary differential equation describing the operations of the still are presented. In addition, the models for the two major inputs of the still, the ambient temperature and the global irradiance, are presented. The mathematical models provide for the study of the effects of many variables on the performance indicators of the solar still - the distillate yield, the water temperature. The variables include depth of water in the still basin, seasons of the year, slope of glass cover, and many variables of construction such as type of glass cover, insulation type and thickness
