Abstract
The supersonic separation is a innovative technology, based on the adiabatic cooling of a swirling gas flow, and arise as promising new technique to remove water and heavy hydrocarbons from a natural gas mixture. However, the process of condensation in compressible flows, is still poorly understood. In this work, low-pressure condensing steam flows were investigated using the method of moments. The numerical results show that coupled nucleation models, such as the Hill's Method of Moments, can be used as a good approximation to analyze compressible flows in nozzle geometries. Also a comparison of the Static Pressure ratio along the nozzle, for different nucleation models was performed. The results were verified against experimental data of high-speed condensing steam measured at low pressure available in the literature.
