Implicit LES Using New Slope Limiters
摘要
In this paper, we study the Implicit Large-Eddy Simulation (ILES) based on new unstructured-grid polynomial-ratio slope limiter functions proposed recently (Jan/2022) by Hiroaki Nishikawa. The slope limiters showed improved resolution characteristics on simple convection test problems. Following that, the ILES approach is tested here on the Taylor and Green vortex test case representing complex flow with transitional and turbulent behavior. The results showed favorable characteristics of the methodology.
