A method to determine stratification efficiency of thermal energy storage processes independently from storage heat losses

A new method for the calculation of a stratification efficiency of thermal energy storages based on the second law of thermodynamics is presented. The biasing influence of heat losses is studied theoretically and experimentally. Theoretically, it does not make a difference if the stratification effi...
