Abstract: The boundary condition at the hot absorber plate in a solar collector will influence the natural convection in the enclosure. For the isoflux boundary condition and an isothermal cold wall an ...

Abstract: The use of porcelain enamelled absorbers in flat plate collectors features longevity thanks to the durability and thermal stability of the enamel finish. The porcelain enamel can be made spectral ...

Abstract: The heat transfer between a cylinder and the surrounding water-saturated soil is studied numerically. Parameters which influence this heat transfer are thermal properties of the soil, dimension ...

Abstract: In this paper a comparison is made between an approximate analytical solution and the numerical finite difference solution for the one dimensional solidification of a phase change material of ...
