Simulation of convective heat removal in a stratified tank of the integrated collector storage solar water heater with builtin heat exchanger

Abstract

Free convective heat removal in a stratified inclined storage tank with builtin heat exchanger is numerically simulated. The effects of coolant flow rate and tank installation angle on heat transfer are investigated. The possibility of the integration of several of tanks into the battery is analyzed. If there are not many tanks, their serial connection in the battery is more preferable than parallel because of the significant output gain.
