Enhanced nozzle design for mitigating the losses arising from non-equilibrium homogeneous condensation

• Investigated non-equilibrium homogeneous condensing flow in modified supersonic Laval nozzles. • Identified key geometric parameters governing supersaturation, nucleation, and droplet growth. • Used a multi-criteria decision approach to select the modified design under independent weighting schemes. • Achieved 72.6% smaller droplets and a 58.4% higher Mach number using the modified SUT de Laval nozzle. Non-equilibrium homogeneous condensation (NHC) significantly affects the efficiency of diverse energy systems, including steam turbines, compressed-air energy storage systems, primary ejector nozzles, and supersonic separator nozzles. In such systems, rapid expansion within supersonic nozzles induces NHC,…
