Resumo

This paper describes a study of the flow and thermal behavior of a thermal energy storage water tank system in which the source of heating is in a side-arm line exterior to, but connected with, the storage tank itself. Buoyancy forces in the side-arm, as a result of water heating, produce a thermosiphon action causing water flow both in the side-arm and in the tank. A small scale laboratory system was designed, fabricated and tested experimentally. An electrical heater in the sidearm line was used as the heat source. Experimental determinations of water flow rates and temperature profiles in the storage tank are given. In addition, predicted results obtained from a computer solution of the equations describing conservation of mass, momentum and energy are presented and are compared with the experimental results.
