Experiments performed on the Impurity Study Experiment (ISX-A) tokamak have shown that poloidally asymmetric injection of hydrogen gas can alter the inward transport of injected impurity atoms. We have compared the observed transport times and the magnitude of the flow reversal effect with a model based on the neoclassical theory of impurity transport and find that the observations are consistent with the theory. However, uncertainities in the radial profiles and the atomic rate coefficients do not permit a truly definitive test of the theory.
