Minimalist turbulent boundary layer model [PDF]

open access: yesPhysical Review E, 2009
We introduce an elementary model of a turbulent boundary layer over a flat surface, given as a vertical random distribution of spanwise Lamb-Oseen vortex configurations placed over a non-slip boundary condition line. We are able to reproduce several important features of realistic flows, such as the viscous and logarithmic boundary sublayers, and the ...

Turbulent Kinetic Energy Production in the Vane of a Low-Pressure Linear Turbine Cascade with Incoming Wakes [PDF]

open access: yesInternational Journal of Rotating Machinery, 2015
Incompressible large eddy simulation and direct numerical simulation of a low-pressure turbine at Re=5.18×104 and 1.48×105 with discrete incoming wakes are analyzed to identify the turbulent kinetic energy generation mechanism outside of the blade ...

Sound radiated from low Mach number turbulent boundary layer flows(Turbulent boundary layer on a smooth plate and over a small forward facing step)

open access: yesJournal of Fluid Science and Technology, 2021
High-resolution numerical simulation has been performed to study aeroacoustic noise radiated from a turbulent boundary layer at freestream Mach number Ma = 0.3, which develops on a smooth flat plate and over a small forward-facing step.

Turbulent and boundary layer characteristics during VOCALS-REx [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
Boundary layer and turbulent characteristics (surface fluxes, turbulent kinetic energy – TKE, turbulent kinetic energy dissipation rate – ϵ), along with synoptic-scale changes in these properties over time, are examined using data collected from 18 ...

Hot-wire experimental investigation on turbulent Prandtl number in a rotating non-isothermal turbulent boundary layer

open access: yesPropulsion and Power Research, 2020
This experiment used a parallel array of hot wire probes to simultaneously measure the temperature and velocity fields in the non-isothermal turbulent boundary layer of a rotating straight channel. The Reynolds numbers are 15,000 and 25,000, respectively.

Dynamics of turbulent western-boundary currents at low latitude in a shallow-water model [PDF]

open access: yesOcean Science, 2015
The dynamics of low latitude turbulent western-boundary currents (WBCs) crossing the Equator are considered using numerical results from integrations of a reduced-gravity shallow-water model.
