We investigate the solutions of partial differential equations describing a two-layered fluid system. The lower layer contains a fastly diffusing, stabilizing substance T and a slowly diffusing, destabilizing substance S. The upper layer contains only the solvent. Double-diffusive convection yields cells in agreement with experiments performed with a tenside (S) and glycerine (T) dissolved in w...
Double diffusive convection is the phenomena that describes driven by two differ-ent densities which have different rates of diffusion. A comparison temperature boundaries when i) both surfaces are set at adiabatic temperature, and ii)upper free surface lower rigid isothermal cases, on tension double in a horizontal composite layer studied analytically using exact method. For cases ii), thermal...
On the onset of triple-diffusive convection in a horizontal layer of nanofluid heated from below and salted from above and below is studied both analytically and numerically. The effects of thermophoresis and Brownian diffusion parameters are also introduced through Buongiorno model in the governing equations. By using linear stability analysis based on perturbation theory and applying normal m...
The Arctic Ocean thermohaline stratification frequently exhibits a staircase structure overlying the Atlantic Water Layer that can be attributed to the diffusive form of double-diffusive convection. The staircase consists of multiple layers of O(1) m in thickness separated by sharp interfaces, across which temperature and salinity change abruptly. Through a detailed analysis of Ice-Tethered Pro...
