Abstract
The thermal performance of a rectangular loop with a horizontal heating segment and a partly cooling vertical leg is studied. By one-dimensional approach, traditional friction factor and empirical correlation, a modified Grashof numberGr* which turns out to be very important in the description of circulation flow is introduced. A new correlation for Nusselt number of the horizontal heater is obtained and the comparison with experimental values shows good agreement.
