Numerical Analysis of the Condensing Steam Flow by Means of ANSYS Fluent and in-House Academic Codes With Respect to the Capacity for Thermodynamic Assessment

In this paper numerical analysis of the condensing steam flow in a converging-diverging nozzle is investigated. The ANSYS Fluent results are compared with in-house academic Computational fluid dynamics code respect to capacity for thermodynamic assessment. “local” real gas equation state used as mathematical complement governing equations code. code, functions well and water physical properties calculated based on IAPWS formulation use UDF. condensation model Fuchs Sutigin correction droplet growth nucleation rate Kantrowitz implemented both CFD codes. obtained experimental data. experiment was carried out using an facility transonic tunnel. investigated geometry adopted under International Wet Steam Experimental Project diverging section expansion 3,000 s ?1 total throat height 40 mm.
