Abstract
A flow adaptive 2D traversing algorithm is developed and demonstrated with measurements in a large axial turbine facility. This novel approach is suited for pneumatic probe and fast response aerodynamic probe measurements. The implementation of the algorithm is fully automated and requires a minimal input, such as blade count and hub and tip diameters, at set-up. The algorithm automatically selects measurement points, such as shear flows, secondary flows, wakes through user-defined detection functions, and adds additional measurement points; therefore higher measurement fidelity in these regions is obtained compared to a traditional measurement method. The flow adaptive 2D traversing algorithm can resolve the overall flow field with 75% fewer measurement points compared to a uniform a measurement grid. This reduction in measurement points results in a measurement time using the flow adaptive algorithm that is 81% quicker than on a uniform measurement grid, without loss of measurement accuracy.
