✦ Synopsis

The purpose of this work is to measure the overall heat transfer coefficient from water to cover in shallow solar stills using yield measurements. The geometry under analysis represents a real solar still operating with laboratory-controlled temperatures and induced heat flows in steady-state. Temperature differences between the water and the glass cover varied from 2 to 16 K, and water temperature from 298 to 353 K, corresponding to the range of heat flows from 0 to 650 W m -2, in accordance with the operation of a solar still in ambient conditions.
