Coherent Solutions and Transition to Turbulence in Two-Dimensional Rayleigh-Bénard Convection
Parvathi Kooloth, David Sondak, Leslie M. Smith
For two-dimensional Rayleigh-Bénard convection, classes of unstable, steady solutions were previously computed using numerical continuation (Waleffe, 2015; Sondak, 2015). The `prim…
Optimal Heat Transport in Rayleigh-Bénard Convection
David Sondak, Leslie M. Smith, Fabian Waleffe
Steady flows that optimize heat transport are obtained for two-dimensional Rayleigh-Bénard convection with no-slip horizontal walls for a variety of Prandtl numbers and Raylei…
Heat Transport by Coherent Rayleigh-Bénard Convection
Fabian Waleffe, Anakewit Boonkasame, Leslie M. Smith
Steady but generally unstable solutions of the 2D Boussinesq equations are obtained for no-slip boundary conditions and Prandtl number 7. The primary solution that bifurcates from…
Local and Nonlocal Dispersive Turbulence
Jai Sukhatme, Leslie M. Smith
We consider the evolution of a family of 2D dispersive turbulence models. The members of this family involve the nonlinear advection of a dynamically active scalar field, the local…
Vortical and Wave Modes in 3D Rotating Stratified Flows: Random Large Scale Forcing
Jai Sukhatme, Leslie M. Smith
Utilizing an eigenfunction decomposition, we study the growth and spectra of energy in the vortical and wave modes of a 3D rotating stratified fluid as a function of . Work…
Self-Similarity in Decaying Two-Dimensional Stably Stratified Adjustment
Jai Sukhatme, Leslie M. Smith
The evolution of large-scale density perturbations is studied in a stably stratified, two-dimensional flow governed by the Boussinesq equations. As is known, intially smooth densit…
