In the ORCHID setup, a circuit is created in which an organic fluid flows, acting as a liquid in the low-temperature section and as a dense vapor in the high-temperature section. The hot vapor can be directed to a supersonic nozzle for fundamental gas dynamics experiments and to a mini ORC turbine for testing purposes.
Research Needs/Objectives:
- Experimental data on non-ideal compressible fluid dynamics with applications in ORC turbines and unconventional turbomachines.
- Accurate measurements for the validation of CFD codes.
- Development of design guidelines for a supersonic mini ORC turbine.
The ORCHID setup is extensive, but DEMO's work primarily focuses on the Nozzle Test Section.
