AB - Heat transfer in the air gap of an horizontal flat plat thermal solar  collector contain partitions attached to its glazing has been studied  numerically. The absorber and the glazing are kept at constant and different  temperatures, while the vertical walls (insulation) were kept adiabatically.  A conjugate formulation was used for mathematical formulation of the problem  and a computer program based on the control volume approach and the SIMPLER  algorithm was used. The main aim of the current paper is to study  numerically the effects of number of fins and their length on the air  pattern and heat transfer. It was observed that the heat transfer rate  through the air gap is affected greatly and hence can be controlled by the  number of attached fins to the glazing of the solar collector as well as the  fin lengths, and the addition of partitions reduces the heat losses by  convection by 90%.
