Observability of Finite-Depth Double-Diffusive Exchange from Sparse Temperature-Salinity Measurements
Sriram P. Kalathoor
Double-diffusive interfaces can support exchange histories that are spatially organized but only sparsely observed. A resolved three-dimensional calculation contains the route by w…
Route survival and spectral modification of finite-depth salt-finger plume forests under imposed mean shear
Sriram P. Kalathoor
Salt-finger plume forests in a finite layer can differ in strength and in the route by which interfacial activity becomes vertically connected. We use direct three-dimensional simu…
Interfacial Spectral Memory as a State Variable for Finite-Depth Salt-Finger Exchange
Sriram P. Kalathoor
Thermohaline interfaces in the ocean are often treated through local double-diffusive favorability, yet finite interfaces can also inherit roughness from prior waves, stirring, int…
Interfacial Roughness Spectra and Finite-Depth Salt-Finger Mixing at a Two-Layer Thermohaline Interface
Sriram P. Kalathoor
Salt fingering drives diapycnal scalar exchange across thermohaline interfaces that are statically stable but double-diffusively unstable. Oceanic interfaces are finite-depth struc…
Receptivity and Biorthogonal Decomposition in a Reacting Temporal Mixing Layer
Sriram P. Kalathoor, Joseph C. Oefelein
We examine receptivity and biorthogonal decomposition in a reacting temporal mixing layer using direct and adjoint eigenmodes of a finite-thickness compressible linearized operator…
Planar Lagrangian transport and scalar-gradient organization in a turbulent reacting shear layer
Sriram P. Kalathoor, Joseph C. Oefelein
We analyze planar Lagrangian transport and scalar-gradient organization in a supersonic, reacting hydrogen-air temporal mixing layer using time-resolved mid-plane data from a three…
