摘要: AbstractIn this paper, the authors explore conditions under which a double-diffusive interface may become unstable. Focus is placed on case of cold, freshwater layer above warm, salty [i.e., diffusive convection (DC) regime]. The “diffusive interface” between these layers will develop gravitationally unstable boundary due to more rapid diffusion heat (the destabilizing component) relative salt. Previous studies have assumed that purely convective-type instability what drives in system and be parameterized by Rayleigh number. test theory conducting both linear stability analysis direct numerical simulations interface. Their reveals transition always occurs as an oscillating mode at numbers much smaller than previously thought. However, findings are ...
