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…
Generalised quasilinear approximations of turbulent channel flow: Part 2. Spanwise scale interactions
Carlos G. Hernandez, Qiang Yang, Yongyun Hwang
Continuing from Part 1 (Hernández \emph{et al.}, \emph{arXiv:2108.12395}, 2021), a generalized quasilinear (GQL) approximation is studied in turbulent channel flow using a flow dec…
Generalised quasilinear approximations of turbulent channel flow: Part 1. Streamwise nonlinear energy transfer
Carlos G. Hernández, Qiang Yang, Yongyun Hwang
A generalised quasilinear (GQL) approximation (Marston \emph{et al.}, \emph{Phys. Rev. Lett.}, vol. 116, 104502, 2016) is applied to turbulent channel flow at ($R…
A local approximation model for macroscale transport of biased active Brownian particles in a flowing suspension
Lloyd Fung, Rachel N. Bearon, Yongyun Hwang
A dilute suspension of motile microorganisms subjected to a strong ambient flow, such as algae in the ocean, can be modelled as a population of non-interacting, orientable active B…
