Simulating the thermal potential for energy storage in an electric water heater tank
MetadataVis full innførsel
This thesis uses a CFD model of an electric water heater tank(EWHT) to investigate the strati cation in the tank during di erent discharge experiments. Strati cation in a tank happens naturally as hot water rises to the top and cold water sinks to the bottom, due to the di erence in density of the water based on the temperature. The simulation found that for higher discharges the strati cation becomes better and it is possible to extract more hot water from the tank than at lower discharges. Although the simulation built in this study can simulate all operations of the tank separately, it has not been successful to build a model that can simulate all operations in the same study.
