In order to experimentally evaluate the performance of turbomachinery, accurate measurements of the flow properties downstream of the turbine rotor are necessary. A key indicator of the efficiency of such equipment is undoubtedly the total pressure, a parameter that is quite challenging to measure when dealing with non-uniform, swirling and potentially non-ideal flows. The measurement of this quantity is intended to be performed on the radial inflow turbine of the TU Delft ORCHID facility, an experimental plant designed to study the performance of Organic Rankine Cycles (ORC). These thermodynamic cycles employ organic working fluids under non-ideal flow conditions and adopt radial inflow turbines for small-scale applications.
