Abstract

In the present paper, a simple mathematical model has been developed for the natural convection flow in the channel-type solar air heater. This type of heaters can be used in a passive solar ventilation system by connecting it from the bottom to the space to be ventilated. The cross-sectionally averaged values of the flow velocity, temperature and pressure are used in the derivation of the governing equations. These equations are numerically solved with thermal boundary conditions similar to that of an actual system, and using appropriate dimensionless groups. A comparison between the temperature variations predicted from this model, and that recorded on a typical system is given in graphical form.
