Keywords: guide vane, wall protuberance, losses, flow separation, turbulence modelling

Detailed investigation of the effect of surface non-conformances on the performance of the low pressure turbine outlet guide vane cascade is presented. For different geometry cases the flow field was monitored and the vane load distributions, downstream secondary flows, and the total pressure loss changes were evaluated.
