The workgroup "Solar Materials" at the Institute of Solar Research is engaged in high-temperature resistant porous materials that can be used in receivers for solar tower power plants. The working area of the material researchers encompasses materials issues regarding the generation of solar electricity, process heat and fuel.
The focus is on functional high-temperature materials, which are investigated and characterized not only for the process of converting radiation to heat (high temperature solar receiver), but also for related - not necessarily solar – topics, so-called spin-off applications. Examples are particulate filters for diesel engines, high-temperature heat exchangers or the open cellular or the effusion cooled combustion chamber wall for gas turbines.
Another area is the description of heat and mass transfer processes in porous materials through innovative numerical models. The work is carried out in cooperation with internal and external partners from industry and research. For the experimental characterization, numerous experimental facilities are available, for instance the Transient Plane Source Technique (Hot Disk), a heat transfer test bench and a system for measuring the dissipative crossmixing.
