Since its initial conception, considerable effort has been expended in determining how to 1) maximise the positive effects of the technique, and as a natural consequence of this, 2) determine which metrics are best suited to quantifying the magnitudes of these ows. One of the issues which has confounded these attempts, has been the inadequacy of contemporary computational models to predict - by some accounts - some of the most apparently desirable quantities (such as loss), accurately.enEexperimental validationEndwall contoursNon-axisymmetricTurbinesArticleBergh, J., Snedden, G.
