Congratulations to the mechanical engineer Stefano Coppini, who just graduated with a master thesis developed at our laboratory with the title “Non-ideal compressible flows of siloxane vapors: an experimental study of expanding flows for ORC applications”.
Congratulations engineer!
A new paper entitled “Experimental evidence of non-ideal compressible effects in expanding flow of a high molecular complexity vapor” was published by Experiments in fluids. It reports experimental results of an experimental campaign carried out with siloxane MDM on supersonic non-ideal nozzle flows.

Nicola Brioschi just graduated in mechanical engineering with a master thesis developed at our lab with the title “Experimental investigation of thermal stability of linear siloxanes mixtures”.
Congratulations!

Organic Rankine cycles gained a relevant role in power production from low to medium temperature sources and for low to medium plant size. Recently, several experimental research projects were developed, to better understand the fundamental physics and plant components functioning. Indeed, the underlying physics and the functioning of such components differ from the one of steam Rankine cycle components, mainly due to the different nature of the organic fluid.

The thesis work consists of a literature research and analysis on projects about ORC applications (turbines, pump, heat exchangers, thermal stability of organic fluids). The student will be assisted by the CREA Lab team.

The TROVA (Test Rig for Organic VApors) is a facility built at CREA Lab (Politecnico di Milano) implementing a batch organic Rankine cycle. The turbine is replaced by a test section, where fluid dynamics measurements are performed. Within a high-pressure reservoir an organic fluid (currently a siloxane) is evaporated up to non-ideal saturated, superheated or supercritical thermodynamic conditions. The vapor is then discharged through a planar, converging-diverging nozzle, the simplest test section which realizes an expansion process comparable to the one occurring within ORC turbine blade channels. The vapor is then condensed and pumped back to the high-pressure reservoir. 
The flow field within the nozzle is characterized by pressure and temperature measurements and by schlieren visualizations, aiming at investigating the different behavior with respect to the ideal gas one. In such a way, also the accuracy of the CFD tools (embedding non-ideal thermodynamic models) employed for the design/analysis of ORC components (and for diverse non-ideal applications) can be verified. Besides nozzle flows, are also of interest the study of non-ideal behavior of oblique and normal shock waves, which are obtained by inserting aerodynamic or bluff bodies within the supersonic flow downstream the TROVA test section.

The thesis consists in performing temperature and pressure measurements and schlieren visualizations in converging diverging nozzles, in the characterization of the fluid dynamics (shock waves) around aerodynamic bodies and in the comparison of experimental values with those obtained by CFD simulations.
