This paper aims to present a CFD investigation into the heat transfer and friction characteristic of a Trombe wall equipped with venetian blinds. This involved (1) development of a CFD model; (2) dedicated experiment for verification of the model; (3) modelling result analyses and conclusion. Based on experimental data, the model was validated and it was able to yield satisfactory predictions. The...
A complete three-dimensional CFD model was developed to investigate the flow and thermal transport in a novel Trombe wall equipped with a venetian blind. The model was involved in flow and heat transfer in the Trombe wall, which was conjugated with heat conduction in the venetian blind. An experimental rig was constructed and utilized to validate the CFD prediction. It was found that the established...
In the design of solar air heaters (SAHs), channel depth is a principal variable to be fixed. In this paper, the effect of the channel depth on the energy gain of type I and type III SAHs has been investigated by computational fluid dynamics (CFD) simulations. Laminar model and k–ω turbulence model of Wilcox are used for the prediction of flow and temperature field in SAHs. Our study shows that the...
A type of ventilated photovoltaic (PV) double-glass window was reported by this paper, which could save energy through the reduction in air conditioning load and generate electric power. Otherwise, it could depress the temperature of PV module, provide comfortable visual and thermal environment and operate as a pre-heating device in winter. Computational fluid dynamics (CFD) was applied to evaluate...
