Magneto Convection in a Layer of Nanofluid With Soret Effect

Linear Stability of Convection in a Viscoelastic Nanofluid Layer

This paper presents a linear stability analysis of natural convection in a horizontal layer of a viscoelastic nanofluid. The Oldroyd B model was utilized to describe the rheological behavior of a viscoelastic nanofluid. The model used for the nanofluid incorporated the effects of Brownian motion and thermophoresis. The onset criterion for stationary and oscillatory convection was derived analyt...

Development of Convection in Binary Mixture with Soret Effect

Molecular diffusion processes are caused by concentration gradients in a multi-component mixture. Noticeable diffusion flux can also be induced by temperature gradients which lead to partial separation of constituent components. This cross effect between temperature and concentration is known as thermo diffusion or Soret effect. This effect can be quite important in the analysis of the distribu...

On the onset of triple-diffusive convection in a layer of nanofluid

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...
