    We experimentally investigate particle migration in a non-Brownian suspension sheared in a Taylor–Couette configuration and in the limit of vanishing Reynolds number. Highly resolved index-matching techniques are used to measure the local particulate volume fraction. In this wide-gap Taylor–Couette configuration, we find that for a large range of bulk volume fraction, $$\unicode[STIX]{x1D719}_{b}\in [20\,\%{-}50\,\%]$$ , the fully developed concentration profiles are well predicted by the suspension balance model of Nott & Brady ( J. Fluid Mech. , vol. 275, 1994, pp. 157–199). Moreover, we provide systematic measurements of the migration strain scale and of the migration amplitude which highlight the limits of the suspension balance model predictions.
