Experimental examination of the MoNiKa-ORC-Turbine and comparison of the results with thermodynamical calculation

The aim of this work is to understand the propane turbine behaviour located at MoNiKa facility in Campus North (KIT). Starting with the thermodynamic simulations, continuing with the selection of different load points to evaluate them experimentally on site and ending with the data analysis to final...
