Measured Instantaneous Viscous Boundary Layer in Turbulent Rayleigh-Bénard Convection

Quan Zhou, Ke-Qing Xia

We report measurements of the instantaneous viscous boundary layer (BL) thickness ${\delta }_v(t)$ in turbulent Rayleigh-Bénard convection. It is found that ${\delta }_v(t)$ obtained from the meas…
