Simulation of Solar Wind Based on K-epsilon (k-a#949;) Turbulence Models [PDF]
Proceedings of the 2016 International Conference on Computer Engineering, Information Science & Application Technology (ICCIA 2016), 2016 The whole interplanetary space is full of solar wind, which is a charged high-velocity flux of particles ejected during coronal expansion. In consideration that solar wind is fluid, and it will be obstructed to generate turbulence when it is dispersed, k-e turbulence models are selected by ANSYS FLUNT in this paper to simulate solar wind as it flows ...

Numerical Investigation of Flow Structures Around a Cylindrical Afterbody Under Supersonic Condition [PDF]
Aerospace Science and Technology, 2015, 2021 Large Eddy Simulation (LES) with dynamic Smagorinsky model has been applied to numerically investigate the complicated flow structures that evolve in the near wake of a cylindrical after body aligned with a uniform Mach 2.46 flow. Mean flow field properties obtained from numerical simulations, such as axial velocity, pressure on base surface, have been

Model-form uncertainty quantification in RANS simulations of wakes and power losses in wind farms [PDF]
, 2021 Reynolds-averaged Navier-Stokes (RANS) is one of the most cost-efficient approaches to simulate wind-farm-atmosphere interactions. However, the applicability of RANS-based methods is always limited by the accuracy of turbulence closure models, which introduce various uncertainties into the models.
