The new Pressure from PIV software package meets the strong demand for direct extraction of full 3D and 2D pressure fields from PIV and Shake-the-Box (4D-PTV) data. With only a few clicks, Pressure from PIV together with LaVision’s DaVis 10 software retrieves and visualizes average pressure fields from all kinds of PIV and PTV velocity data either imported to or directly computed by DaVis. For time-resolved data, even the instantaneous pressure can be evaluated.Commonly, pressure measurements are retrieved pointwise, for instance with pressure taps or Pitot tubes. Instrumentation of wind tunnel models with pressure sensors is time consuming, complex and expensive. In the European NIOPLEX project, several universities and LaVision joined forces to develop a non-intrusive, direct method for pressure retrieval in complete volumes. This project finally pinpointed practical ways for pressure calculation from PIV/PTV measurements.
