Near-wall turbulence intensity as
Yongyun Hwang
In this study, asymptotic scaling of near-wall streamwise turbulence intensity ( is the friction velocity) is theoretically explored. The three scaling…

Multi-scale invariant solutions in plane Couette flow: a reduced-order model approach
Matthew McCormack, André V. G. Cavalieri, Yongyun Hwang
Plane Couette flow at Re=1200 (based on the channel half-height and half the velocity difference between the top and bottom plates) is investigated with a spatial domain designed t…

A data-driven quasi-linear approximation for turbulent channel flow
Jacob Holford, Myoungkyu Lee, Yongyun Hwang
A data-driven implementation of a quasi-linear approximation is presented, extending a minimal quasi-linear approximation (MQLA) (Hwang & Ekchardt, J. Fluid Mech., 2020, 894:A23) t…
