Effect of rotation and non-uniform temperature gradients on the onset of Marangoni convection in a fluid with suspended particles under microgravity condition

Abstract

The effect of six different non-uniform temperature gradients and rotation on the onset of Marangoni convection in a fluid which has suspended particles in it and confined between an upper free, adiabatic and lower rigid, isothermal boundaries under microgravity condition has been discussed using Linear Stability Analysis. The Eigen values are obtained by using the single term Galerkin Technique followed by matrix method. The microrotation is assumed to be vanished at the boundaries. The effect of Taylor number and different micropolar fluid parameters on the onset of stationary convection has been analyzed by neglecting the body force. Also the comparative influence of six various non-uniform temperature profiles on the onset of Marangoni convection has been studied.
