National audienceWe present a linear and a weakly non-linear analysis of Rayleigh-Bénard thermo-convective instabilities for shear-thinning fluids with thermo-dependent viscosity. Our objective is to study the influence of the nonlinear variation of the viscosity with the shear rate and the thermo-dependency of the rheological parameters on the nature of the bifurcation and on the competition between different convection patterns. This study complements the work of Bouteraa et al. [1] where the temperature dependence of the viscosity has not been taken into account. In this study, we adopt the Carreau model with an exponential temperature dependence of µ(T).Nous présentons une analyse linéaire et faiblement non linéaire des instabilités the...
