ABSTRACT. An experimental investigation was carried out to explain the stratification behavior during the discharging mode. The standard tank, which is a rectangular design. Three tests have been explained. The first test was a side-inlet water jet together with a rectangular tank, and the other two tests are demonstrated by the insertion of various designs of curved baffles at the bottom of the tank in each test, which is expected to damp the turbulence of the water inlet jet. All these tests are completed at high and low consumption rates of 12 L/min and 6 L/min, respectively. A transient temperature distribution, stratification efficiency, and Richardson number are performance indicators for the thermal storage tanks. It has been found that the curvature of the baffle type B gives more stable thermal stratification in water layers and a clear difference in enhancement compared with a conventional tank during high and low consumption rates.
