DETERMINATION OF FLOW VELOCITY UNDER FREE CIRCULATION OF HEAT CARRIER IN SOLAR WATER HEATING SYSTEMS

An analytical model for the flow of heat carrier in natural-circulation (thermosiphon) solar water heaters is presented. A differential equation for the flow velocity   is derived, accounting for the gravitational driving head due to density differences between hot and cold fluid a...
