Summary on Grant Application Form |
Wake-induced transition typically occurs in multi-stage turbomachine. It affects the aerodynamic performance of turbine and compressor blades considerably. Although the various mechanisms of wake-induced transition have now been identified, the detailed processes are not yet understood. In this joint proposal, the University of Manchester will use a novel combination of PIV and liquid crystal flow visualization technique to conduct detailed measurements of wake-induced transitional events occurring in an attached laminar boundary layer and a separated boundary layer with a separation bubble. The University of Cambridge will use bar-passing cascades to study the breakdown mechanism initiated by incoming wakes in separated boundary layers and in the mixed-mode region of transitory separated/attached boundary layers that can arise when wake-induced transition begins before but is not complete by the point of laminar separation. The aims are to obtain a better understanding of the mechanisms of wake-induced transition in attached, separating and separated flows and to provide benchmark quality data for developing and validating computational models.
