SFB 561:  Thermally Highly Loaded, Porous and Cooled Multi Layer Systems for Combined Cycle Power Plants

Subject Area Materials Science and Engineering
Term from 1998 to 2010
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5482623
 
Within the frame of the collaborative research centre different fields of research are co-operating in order to develop the fundamentals related to thermo fluid dynamics, structural mechanics and manufacturing processes for specific components used in combined gas turbine and steam turbine power plants. The aim is to achieve total efficiencies of approximately 65 %. Thermally highly loaded parts such as walls of the combustion chamber, gas turbine blades and inlet areas of high temperature steam turbines are supposed to be cooled using effusion/transpiration cooling technology. For this reason, porous composite materials manufactured by casting or microdrilling and covered with thermal barrier coating are investigated. For dewatering in low pressure turbines open porosity metallurgical composite materials are to be developed. The effect of coolant flow out of the porous surface and of the materials properties on the overall process and on the design parameters to be optimised are subject to a special subproject.
