A highly efficient numerical approach based on multigrid and preconditioning methods is
developed for modeling 3D steady and time-dependent incompressible flows. Thek-ω …

Many researchers use a time-lagged or loosely coupled approach in solving the Navier–
Stokes equations and two-equation turbulence model equations in a time-marching method …

This paper describes a novel approach in simulating laminar to turbulent transition by using
two‐equation models. The Total Stresses Limitation (TSL) concept is used to make the two …

This paper aims to present some of the experimental and numerical results obtained with the
NASA–Boeing Common Research Model at ONERA. The wind tunnel model used in the …

Simulating unsteady turbulent flow in turbomachines is still challenging due to the
complexity of blade geometry and relative motion between rotor and stator. This study …

This work presents an actuator disk-like body force method designed for propeller modeling,
which is based on a full coupling between computational fluid dynamics (CFD) and blade …

This paper investigates the influence of the torque ratio, at constant total thrust, on the
interaction noise of a generic counter-rotating open rotor in pusher configuration. It is shown …

Reynolds-averaged Navier–Stokes (RANS), unsteady RANS (URANS), and large eddy
simulation (LES) numerical approaches are clear candidates for the understanding of …

When two-equation turbulence models are used, unrealistically large values of turbulence
variables can appear due to the infringement of a realizability condition or to numerical error …

This study presented a hybrid model method based on proper orthogonal decomposition
(POD) for flow field reconstructions and aerodynamic design optimization. The POD basis …
