Abstract

The process of rapid hot water displacement from the inclined tank of an accumulative solar water heater was simulated, the thermocline dissipation pattern was studied, and the effect on the degree of stratification of the flow rate, the angle of installation of the tank, and the relative position of intake and outtake pipes were determined. Conclusions are presented on the preferential arrangement of hydraulic connections and recommended water pumping, as well as exergetic assessments of the degree of stratification in the accumulator tanks.
