Modeling and assessment of two-phase transonic steam flow with condensation through the convergent-divergent nozzle

Transonic Potential Flows in A Convergent–Divergent Approximate Nozzle

In this paper we prove existence, uniqueness and regularity of certain perturbed (subsonic–supersonic) transonic potential flows in a two-dimensional Riemannian manifold with “convergent–divergent” metric, which is an approximate model of the de Laval nozzle in aerodynamics. The result indicates that transonic flows obtained by quasi-one-dimensional flow model in fluid dynamics are stable with ...

Numerical Simulation of Non-Equilibrium Two-Phase Wet Steam Flow through an Asymmetric Nozzle

The present study reported of the numerical investigation of a high-speed wet steam flow through an asymmetric nozzle. The spontaneous non-equilibrium homogeneous condensation of wet steam was numerically modeled based on the classical nucleation theory and droplet growth rate equation combined with the field conservations within the computational fluid dynamics (CFD) code of ANSYS Fluent 13.0....

Prediction of Radiation Heat Transfer from Combustion Gases in a Convergent- Divergent Nozzle Using Zoning Method

Numerical analysis of supersonic- subsonic flow in the convergent- divergent nozzle along with the shock and comparison with analytical results

conservation form and artificial non-viscosity term is used to prevent high vibrations in shock area in momentum equation. Because of changing cross section along the flow, all fluid characteristics would be considered a function of x. so by choosing an appropriate control volume, the main equations include continuity, momentum and energy were discrete .To solve the main equations, McCormack ex...
