Modelling free convection in a trombe wall

In this paper, the convective laminar heat transfer between the channel surfaces of the Trombe wall and a modified version of the conventional Trombe wall have been investigated. Velocity profiles, temperature profiles, and pressure defect have been investigated for the conventional Trombe wall, when the temperature of the masonry wall is not uniform but of the form Tw(x) = Tg+Axn. The variation of fluid velocity, temperature and the average Nusselt number have been determined numerically for selected tilt angles of the glass wall for the modified version of the Trombe wall. It was found that there is a significant effect of the glass wall inclination on the average Nusselt number.
