Triadic energy cascades and linear amplification mechanisms in supersonic turbulent boundary layers over curved walls
Lucas Feitosa de Souza, Hugo F. da Silva Lui, William Roberto Wolf +1
Direct numerical simulations are performed to investigate supersonic turbulent boundary layers subjected to continuous concave and convex surface curvatures. Scale-resolved spectra…
Active flow control of vertical-axis wind turbines: Insights from large-eddy simulation and finite-time resolvent analysis
Lucas Feitosa de Souza, Renato Fuzaro Miotto, William Roberto Wolf
Active flow control is applied to improve the aerodynamic performance of a NACA0018 airfoil operating as a single-bladed vertical axis wind turbine (VAWT). Results computed by wall…
Duty-cycle actuation for drag reduction of deep dynamic stall: Insights from linear stability analysis
Lucas Feitosa de Souza, William Roberto Wolf, Maryam Safari +1
A flow control framework based on linear stability analysis is proposed focusing on reducing the aerodynamic drag due to dynamic stall through a finite-window temporal actuation. T…
Analysis of transient and intermittent flows using a multidimensional empirical mode decomposition
Lucas F. de Souza, Renato F. Miotto, William R. Wolf
Modal decomposition techniques are important tools for the analysis of unsteady flows and, in order to provide meaningful insights with respect to coherent structures and their cha…
