Abstract


This article is concerned with the CFD investigations of the effect of placing a metallic mesh inside the channel of the simplified passive solar collector design. Numerical results obtained demonstrated that such a design would improve the heat transfer from the walls of channels to the liquid and therefore would result in the hot water production capacity of the solar collector. Using numerical models that can predict the physical performance of a design project, it is possible to find, optimised solutions without creating a large and expensive series of models.
