      abstract     = {We 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.
