Abstract: The objective of this work was to examine radial mixing in an axial turbine from a number of different perspectives. These include: (1) its impact on the spanwise distributions of the force on the airfoils and the change in the fluid momentum as it passed between them, (2) the mixing coefficient distribution based on measured secondary flow velocities, and (3) comparisons of measured and calculated profile redistribution for an axisymmetric inlet profile and for profiles generated by introducing hot and cold streaks upstream of the turbine. It was seen that a simple diffusive transport model could give a good prediction of most of the measured results.
