000134256 520__ $$aWe present here the numerical simulation on SCC (shear-rate gradient concentration coupling) instability on colloidal sphere in both Cartesian and cylindrical geometries.   The flow instability due to coupling between shear-gradients and mass transport has been discussed through the linear stability analysis and shear-induced distortion of the pair-correlation function, which is related to shear rate dependent chemical potential [1-4].   In this poster, behaviors of concentration and shear rate profiles under various concentration, apparent shear rate and chemical potential are calculated to compare the result with the stability analysis discussed in Ref. [4]. In case of a cylindrical couette, the effect of curvature is discussed as a function of stability criterions.     References:  [1] J.K.G.
