DLR comparison of the evaluations of image 03 and image 04 from T1.2 database

Abstract

A database for the exchange of PIV recordings and the results of their evaluation was established at DLR Göttingen for the EUROPIV project. A file format based on netCDF was defined for the exchange of the data between the EUROPIV partners. DLR contributed two PIV recordings to this database: Image 03 representing a transonic flow with a shock above an airfoil at Ma=0.75 and Image 04 representing the flow field behind a grid in a wind tunnel with very small velocity fluctuations. This report describes the EUROPIV database comprising 151 different PIV recordings (189 MByte) and the EUROPIV file format for data exchange. Furthermore it compares the evaluations contributed by different EUROPIV partners for Image 03 and Image 04
