    Abstract: In this paper, we have presented the axisymmetric stagnation flow of a micropolar fluid in a moving cylinder. The governing equations of motion, microrotation and energy are simplified with the help of suitable similarity transformations. System of six nonlinear coupled differential equations has been solved analytically with the help of strong ana... Show More

    Abstract: Linear thermal instability analysis of a ferrofluid layer confined between in Hele-Shaw cell is investigated. The stability theory is based upon perturbation method and normal mode technique and the resulting equations are solved by using Galerkin weighted residuals method to find expressions for Rayleigh number and critical Rayleigh number. ‘Princ...
