Disturbance of Stratification Caused by Direct Horizontal Inlets into a Water Storage Tank

The stratification efficiency of direct combi-storage inlets has a decisive influence on the energetic efficiency of solar thermal systems and even more of heat pumps that are connected to combi-storages. In this work, the effect of different geometrical designs and mass flow rates on stratification of the storage is studied for direct storage inlets with computational fluid dynamics. Selected experiments are validated with laboratory tests.
