Fluid Flow Analysis of Porous Metals in Solar Thermal Applications
Keywords:
metal foam, flow analysis, finite element method, solar flat collector.Abstract
Presented paper dealt with use of porous materials, in this case metal foam, in the solar thermal applications. First part of paper is engaged to the fluid flow analysis in the spatial structure of metal foam body, which represents simplified form of the solar absorber. From application point of view were desired properties of foam structure described with using of CFD tools based on finite element method. As a boundary conditions of simulation were set different heat transfer flow rates and properties of metal foam which is characterized by average pore diameter. According to obtained results of simulations were identified optimal conditions and flow regimes for metal foam that will be used as a full flow solar flat collector.
