Effect of Cross Diffusion on the Onset of Double Diffusive Marangoni Convection in a Fluid Layer
Journal Title: JOURNAL OF ADVANCED RESEARCH IN APPLIED MECHANICS & COMPUTATIONAL FLUID DYNAMICS - Year 2018, Vol 5, Issue 3
Abstract
In the present study, double-diffusive convection in a horizontal layer of a fluid in the presence of temperature gradients (Soret effects1∆) and concentration gradients (Dufour effects2∆) are considered. The onset of convection is studied using linear stability analysis for temperature and concentration boundary conditions. The effects of critical Marangoni numbers, Dufourcoefficient1∆, Soret coefficient2∆and diffusivity ratioτon stationary, oscillatory convection are shown graphically and the effects of various parameters have been discussedin detail.
