An efficient correction for the finite-size effects of multihole pressure probes in velocity gradients
Övrigt konferensbidrag, 2008

This study describes an implementation and verification of an efficient and reliable correction for the finite-size effects of pressure probes. The performance of the correction in application to the highly three-dimensional flow downstream of the linear cascade is scrutinized through a detailed side-by-side comparison with corresponding cross hot-wire data. The influence of the correction on all three velocity components, flow streamlines and streamwise vorticity fields is thoroughly examined. The study demonstrates that the correction lead to a significant improvement of the velocity data. A very good performance of the correction for the finite-size effects of pressure probes presented in this study allow us to recommended it as a mandatory step in postprocessing procedures for multi-hole pressure probes.
