Aerodynamic comparison and validation of rans, K-ω, standard K-ɛ and URANS simulations of flat plate film-cooling
… work focuses on the numerical investigation of RANS and URANS analyses on a flat plate film cooling. The investigation aims to provide comparison between various turbulent models available for the Reynolds Average Navier Stokes (RANS) analyses and extended to unsteady Reynolds Average Navier …

An hp-Adaptive Petrov-Galerkin Method for Steady-State and Unsteady Flow Problems
… on numerous cases using the Euler and Reynolds Average Navier-Stokes (RANS) equations, equipped with a modified Spalart-Allmaras (SA) turbulence model. Also, a PDE-based artificial viscosity has been added to the governing equations, to stabilize the solution in the vicinity of shock …

Experimental and Numerical Study of Multi- Phase Flow in a Coaxial Air Jet
… results of numerical simulations using different Reynolds Average Navier Stokes (RANS) models. The k-ε realizable model provided the best agreement with the axial velocity measurements, but all the RANS models predicted a recirculation zone immediately downstream of the central jet that did not …

Simulations of droplet dispersion in the wakes of cylinders and icing tunnel spray bars
… air flow was investigated with a hybrid Reynolds-Averaged Navier-Stokes/Large-Eddy Simulations approach scheme. In the first study, droplets were injected downstream of a cylinder at sub-critical conditions (i.e. with laminar boundary layer separation). A stochastic continuous random walk …
