Pressure profile optimisation of a nozzle for wet-to-dry expansion

Wet-to-dry expansion within the nozzle guide vane of an ORC turbine has been proposed as a means to improve the power output of ORC systems for waste-heat recovery (< 250 °C). However, given the rapid fluid acceleration in the stator, the phases can develop significant velocity and temperature disparity due to the density difference and finite rate of interphase heat transfer. Since
