Abstract
The effects of hydrostatic, hydrodynamic, porosity and pressure drop on the heat transfer characteristics of a solar heating panel incorporating a parabolic trough collector (PTC) and porous packed bed are investigated experimentally. The results show that a solar collector installed with only a PTC is able to improve the thermal absorption of the working fluid. Through the addition of a porous media into parts of the receiver tubes, the thermal efficiency of the collector can be further enhanced. The heat transfer performance increases with the decrease in porosity and mass flow rate. It is also found that a porous medium is able to increase the rate of heat transfer during the transient hydrostatic experiment, whereas the rate of heat transfer remains constant in the hydrodynamic study where non-local-thermal-equilibrium (NLTE) becomes dominant. Lastly, it is critical to form a non-sintered porous packed bed using particles with uniform diameters to avoid extra internal pressure losses.
