An approximate analytical solution for the prediction of transient response of the Trombe wall Free convective turbulent flow within the trombe wall channel.

A numerical solution for two-dimensional free convective laminar flow in the Trombe wall channel has recently been presented by Akbari and Borgers (1). Their analysis assumed no flow losses in the channel entrance and exit, other than the exit dynamic head (loss coefficient k=1), however the actual coefficient for combined inlet and exit losses.

The natural convective heat transfer and air movement in a Trombe wall solar passive system has been studied analytically and numerically. Three Trombe wall channel geometries including the parallel channel with axial inlet and exit, parallel channel with side vents and Trombe wall channel coupled to the room have been considered.
