Using two cameras the spatial components of particle motion are o��tained, from these the three-dimensional velocity fi eld in the measuring plane is determined. Velocity fi elds can ��e visualised and are well suited to the validation of computational �� uid dynamics results. Similarly, the conventional �� ow characteristics ��mass �� ow, Tippelmann swirl and tumble numbers) can be derived from the velocity fi elds, allowing a ��uick comparison with results of the integral momentum measuring technique. In addition, other characteristics of the �� ow fi eld, such as the position and orientation of the swirl and tumble axes or the omega tumble value, can be determined, further contributing to the analysis and documentation of the in�� uences of air-conducting components. BENEFITS AT A GLANCE • Precise three-dimensional recording of the velocity fi eld �� Velocity fi elds from different planes can be combined to visualise the spatial velocity distribution • Measurement close to the combustion chamber surface of the cylinder head PIV Flow Test Benches Stereo PIV • Automated measurement sequence • Comparability to integral momentum measuring method according to Tippelmann • Safety requirements for industrial use are met Battery Test Systems E-Motor Test Systems Inverter Test Systems E-Integration Test Systems E-Power Analysis System ��lo�� ��e��t ��enc��e�� Thermal Test Systems MBD on the Virtual Testbed Engine Test Systems End of Line Test Systems Real Life Test Systems Driveline Test Systems Fuel and Lube Test Systems Emission Test Systems an������ertifi��cation Vehicle Test Systems Racing Test Systems
