Double-Diffusive Convection at Low Prandtl Number: Supplemental Video

A supplemental video from the 2018 review by Pascale Garaud, "Double-Diffusive Convection at Low Prandtl Number," from the Annual Review of Fluid Mechanics. 

Shown: Temporal evolution of the compositional perturbations C in a simulation at Pr = τ = 0.33, R ₀ ^-1 = 1.15, in a large domain of size 200d x 200d x 400d. After a brief phase of oscillatory double-diffusive convection (ODDC) (which can be difficult to see in this fixed-scale movie), eight layers spontaneously appear. The layers progressively merge until only two are left, at which point the movie ends. These layers ultimately merge much later (not shown). Simulation from Wood et al. (2013).
