Investigation of heat loss from a solar cavity receiver
This study examines experimentally the heat loss from a model solar cavity receiver. For this purpose, laboratory-scale cylindrical cavity models with geometric aspect ratios (cavity length to diameter) of 1 and 2, and aperture opening ratios (aperture diameter to cavity diameter) of 0.5 and 1, were built. Each cavity was subjected to constant boundary heat input via heating cables, and was ope...
متن کاملComputational and experimental investigations into cavity receiver heat loss for solar thermal concentrators
Tubular cavity receivers offer excellent prospects as low-cost, high-efficiency heat collection elements for paraboloidal dish solar-thermal concentrators, as well as for central tower systems. Major heat loss mechanisms for these receivers are convection and radiative emission, as well as reflection and spillage (non-capture). Compared to glazed receivers, convection heat loss can be quite a l...

In this paper effect of opening ratio and operating temperature on convective and radiative losses from cavity receiver of solar concentrators are presented. Convective and radiative
متن کاملAn Air-Based Cavity-Receiver for Solar Trough Concentrators
A cylindrical cavity-receiver containing a tubular absorber that uses air as the heat transfer fluid is proposed for a novel solar trough concentrator design. A numerical heat transfer model is developed to determine the receiver’s absorption efficiency and pumping power requirement. The 2D steady-state energy conservation equation coupling radiation, convection and conduction heat transfer is ...
متن کاملEnhancement in energy and exergy efficiency of a solar receiver using suspended alumina nanparticles (nanofluid) as heat transfer fluid
An experimental and theoretical energy and exergy analysis was conducted for a cylindrical cavity receiver employed in a parabolic dish collector. Based on simultaneous energy and exergy analysis, the receiver average wall temperature and overall heat transfer coefficient were determined. A simplified Nusselt number for Heat Transfer Fluid (HTF) through the receiver as a function of Reynolds an...
