Solar loops use water to heat a thermal storage tank containing water too. The cycle employs solar erergv to vaporize the water and the steam drives an engine. For these purpose, flash evaporation experiments in the pool were carried out. If temperature change, due co flash evaporation, is less than 5℃ (error ia less than 5%), the simiplification of Clapeyron equation is correct.
An optimum flash-down and cross sectional area of heatstorage for a required steam flow rate were found for steady state conditions. It will be best to use the storage vessel in a shape of frustum cone. With the evaporation of water, the water level will fall. this new level will have a larger cross-sectional area requiring less flash down to reach the saine steam flow rate.
