A sensor-restrained artificial shear diffusivity for large-eddy simulations of vortex-dominated compressible flows
Jean Hélder Marques Ribeiro, Hugo Felippe da Silva Lui, William Roberto Wolf
We propose a sensor-restrained model for the shear viscosity term within the localized artificial diffusivity (LAD) scheme to stabilize compressible large-eddy simulations with low…
Triglobal resolvent-analysis-based control of separated flows around low-aspect-ratio wings
Jean Hélder Marques Ribeiro, Kunihiko Taira
We perform direct numerical simulations (DNS) of actively controlled laminar separated wakes around low-aspect-ratio wings with two primary goals: (i) reducing the size of the sepa…
An Invitation to Resolvent Analysis
Laura Victoria Rolandi, Jean Hélder Marques Ribeiro, Chi-An Yeh +1
Resolvent analysis is a powerful tool that can reveal the linear amplification mechanisms between the forcing inputs and the response outputs about a base flow. These mechanisms ca…
