Abstract
The quantitative whole field flow visualization technique of PIV has over the last three years been successfully demonstrated for transonic flow applications. A series of such measurements has been made at DRA Pyestock. Several of the development stages critical to a full engine application of the work have now been achieved at DRA Pyestock using the Isentropic Light Piston Cascade test facility operating with high inlet turbulence levels: (1) A method of seeding the flow with 0.5 micron diameter styrene particles has provided an even (1 mm by 1 mm) coverage of the flow field. (2) A method of projecting a 1 mm thick high power Nd/YAG laser light sheet within the turbine stator cascade. This has enabled a complete instantaneous intra-blade velocity mapping of the flow field to be visualized. (3) Finally, software has been developed to automatically analyze the data.
