Resolvent-based predictions for turbulent flow over anisotropic permeable substrates
Andrew Chavarin, Garazi Gomez-de-Segura, Ricardo Garcia-Mayoral +1
Recent simulations indicate that streamwise-preferential porous materials have the potential to reduce drag in wall-bounded turbulent flows(Gomez-de-Segura & Garcia-Mayoral 2019).…

Resolvent-based design and experimental testing of porous materials for passive turbulence control
Andrew Chavarin, Christoph Efstathiou, Shilpa Vijay +1
An extended version of the resolvent formulation is used to evaluate the use of anisotropic porous materials as passive flow control devices for turbulent channel flow. The effect…

Resolvent Analysis for Turbulent Channel Flow with Riblets
Andrew Chavarin, Mitul Luhar
This paper extends the resolvent formalism for wall turbulence proposed by McKeon and Sharma(2010) to account for the effect of streamwise-constant riblets. Under the resolvent for…
