DOI: 10.1016/j.ijheatfluidflow.2016.12.005
Abstract: We present an extension that allows a recently proposed structure-based model for turbulent scalar transport to account for buoyancy effects. The proposed model is based on a generalization of the Interactive Particle Representation Model (IPRM)… read more here.

DOI: 10.1017/jfm.2019.377
Abstract: The linear stability of plane Couette flow is investigated when the plates are horizontal, and the fluid is stably stratified with a cubic basic density profile. The disturbances are treated as inviscid and diffusion of… read more here.

DOI: 10.1017/jfm.2019.577
Abstract: Turbulent structures in stably stratified shear layers are studied with direct numerical simulation. Flow visualization confirms the existence of hairpin vortices and highly elongated structures with positive and negative velocity fluctuations, whose streamwise lengths divided… read more here.

DOI: 10.1088/1402-4896/ab022a
Abstract: In this paper, the properties of stably stratified turbulence (SST) and turbulent thermal convection are contrasted. A key difference between these flows is the sign of the kinetic energy feed by buoyancy, $\mathcal{F}_B$. For SST,… read more here.

DOI: 10.1103/physrevfluids.8.054501
Abstract: Inertial particles in stably stratified flows play a fundamental role in geophysics, from the dynamics of nutrients in the ocean to the dispersion of pollutants in the atmosphere. We consider the Maxey-Riley equation for small… read more here.

DOI: 10.1175/jpo-d-18-0139.1
Abstract: Turbulent mixing in the interior of the oceans is not as well understood as mixing in the oceanic boundary layers. Mixing in the generally stably stratified interior is primarily, although not exclusively, due to intermittent… read more here.
