An efficient correction for the finite-size effects of multihole pressure probes in velocity gradients
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 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.
