Recycled Material for Sensible Heat Based Thermal Energy Storage to be Used in Concentrated Solar Thermal Power PlantsCurrent technologies of concentrated solar power plants (CSP) are under extensive industrial development but still suffer from lack of adapted thermal energy storage (TES) materials and systems. In the case of extended storage (some hours), thousands of tonnes of materials are concerned leading to high investment cost, high energy and GHG contents and major conflicts of use. In this paper,... ... hiện toàn bộ

Numerical Implications of Solidity and Blade Number on Rotor Performance of Horizontal-Axis Wind TurbinesA numerical study was conducted to examine the impact of rotor solidity and blade number on the aerodynamic performance of small wind turbines. Blade element momentum theory and lifting line based wake theory were utilized to parametrically assess the effects of blade number and solidity on rotor performance. Increasing the solidity beyond what is traditionally used for electric generating... ... hiện toàn bộ

Natural Convection and Conduction in Porous Wall, Solar Collector Systems Without VentsSteady natural convection heat transfer has been studied in porous wall, solar collector systems. The boundary conditions were: two isothermal walls at different temperatures, two horizontal bounding adiabatic walls, and either uniform or nonuniform heat generating porous layer without vents. The aspect ratio A was from 0.5 to 1.4. The Rayleigh number varied from 103 to 108. The Darcy numb... ... hiện toàn bộ

Design of an Experimental Solar-Powered, Solid-Adsorption Ice MakerPurely thermal heat pumps can be devised with adsorbate/solid adsorbent pairs, for example for refrigeration purposes. As each cycle consists of two periods, i.e., heating/desorption/condensation and cooling/adsorption/evaporation, this mode of operation is well-suited to solar energy. After experiments with the Zeolite/Water pair, a solar-powered ice maker was designed with the Activated ... ... hiện toàn bộ

Mean and Peak Wind Loads on HeliostatsMean and peak wind loads on flat rectangular or circular heliostats were measured on models in a boundary layer wind tunnel which included an atmospheric surface layer simulation. Horizontal and vertical forces, moments about horizontal axes at the ground level and at the centerline of the heliostat, and the moment about the vertical axis through the heliostat center were measured. Results... ... hiện toàn bộ

Theoretical Analysis of a Water Desalination System Using Low Grade Solar HeatTheoretical analysis of a solar desalination system utilizing an innovative new concept, which uses low-grade solar heat, is presented. The system utilizes natural means of gravity and atmospheric pressure to create a vacuum, under which liquid can be evaporated at much lower temperatures and with less energy than conventional techniques. The uniqueness of the system is in the way natural ... ... hiện toàn bộ

The Effect of a Thermotropic Material on the Optical Efficiency and Stagnation Temperature of a Polymer Flat Plate Solar CollectorSolar hot water and space heating systems constructed of commodity polymers have the potential to reduce the initial cost of solar thermal systems. However, a polymer absorber must be prevented from exceeding its maximum service temperature during stagnation. Here, the addition of a thermotropic material to the surface of the absorber is considered. The thermotropic layer provides passive ... ... hiện toàn bộ
