Rayleigh-Benard-Marangoni electro-convection in a dielectic micropolar fluid /

Mathematics

The linear analysis of Rayleigh-B??nard-Marangoni convection in dielectric micropolar fluid is studied using the Galerkin technique. In the case of Rayleigh ?? B??nard convection, the eigenvalue is obtained for free - free, rigid ?? free and rigid ?? rigid velocity boundary combinations with isothermal and adiabatic on the spin-vanishing boundaries. A linear stability analysis is performed. The influence of various parameters on the onset of convection has been analyzed. In the case of Marangoni and Rayleigh-B??nard-Marangoni convection the eigenvalues are obtained for an upper free / adiabatic and lower rigid / isothermal boundaries. The microrotation is assumed to vanish at the boundaries. The influence of various parameters on the onset of convection has been analyzed and their comparative influence on onset is discussed.
