Logarithmic scaling of higher-order temperature moments in the atmospheric surface layer
Kelly Y. Huang, Matt K. Fu, Clayton P. Byers +2
A generalized logarithmic law for high-order moments of passive scalars is proposed for turbulent boundary layers. This law is analogous to the generalized log law that has been pr…
Effects of surfactants on bubble-induced turbulence
Tian Ma, Hendrik Hessenkemper, Dirk Lucas +1
We use experiments to explore the effect of surfactants on bubble-induced turbulence (BIT) at different scales, considering how the bubbles affect the flow kinetic energy, anisotro…
Asymptotic closure model for inertial particle transport in turbulent boundary layers
Yan Zhang, Guiquan Wang, Andrew D Bragg
Transport equations for heavy inertial particles in turbulent boundary layers may be derived from an underlying phase-space probability density function (PDF) equation. These equat…
Lagrangian model for passive scalar gradients in turbulence
Xiaolong Zhang, Maurizio Carbone, Andrew D. Bragg
The equation for the fluid velocity gradient along a Lagrangian trajectory immediately follows from the Navier-Stokes equation. However, such an equation involves two terms that ca…
A stochastic model for the residence time of solid particles in turbulent Rayleigh-Bénard Flow
Colin J. Denzel, Andrew D. Bragg, David H. Richter
The Pi Chamber, located at Michigan Technological University, generates moist turbulent Rayleigh-Bénard flow in order to replicate steady-state cloud conditions. We take inspiratio…
The effect of tilt on turbulent thermal convection for a heated soap bubble
Xiao-Qiu He, Yong-Liang Xiong, Andrew D. Bragg +2
We use direct numerical simulation (DNS) to explore the effect of tilt on two-dimensional turbulent thermal convection on a half-soap bubble that is heated at its equator.In the DN…
