Event-based imaging velocimetry using pulsed illumination
Christian E. Willert
The paper addresses the shortcoming of current event-based vision (EBV) sensors in the context of particle imaging. Latency is introduced both on the pixel level as well as during…
Event-based Imaging Velocimetry -- An Assessment of Event-based Cameras for the Measurement of Fluid Flows
Christian Willert, Joachim Klinner
Contrary to conventional frame-based imaging, event-based vision (EBV) or dynamic vision sensing (DVS) asynchronously records binary signals of intensity changes for given pixels w…
Investigation of Large Scale Motions in Zero and Adverse Pressure Gradient Turbulent Boundary Layers Using High-Spatial-Resolution PIV
Muhammad Shehzad, Bihai Sun, Daniel Jovic +6
High-spatial-resolution (HSR) two-component, two-dimensional particle-image-velocimetry (2C-2D PIV) measurements of a zero-pressure-gradient (ZPG) turbulent boundary layer (TBL) an…
Distortion correction of two-component - two-dimensional PIV using a large imaging sensor with application to measurements of a turbulent boundary layer flow at
Bihai Sun, Muhammad Shehzad, Daniel Jovic +6
In the past decade, advances in electronics technology have made larger imaging sensors available to the experimental fluid mechanics community. These advancements have enabled the…
Extensive characterization of a high Reynolds number decelerating boundary layer using advanced optical metrology
C. Cuvier, S. Srinath, M. Stanislas +14
An experiment conducted in the framework of the EUHIT project and designed to characterize large scale structures in an adverse pressure gradient boundary layer flow is presented.…
Megahertz Schlieren Imaging of Shock Structure and Sound Waves in Under-Expanded, Impinging Jets
Christian Willert, Daniel Mitchell, Julio Soria
The accompanying fluid dynamics videos visualize the temporal evolution of shock structures and sound waves in and around an under-expanded jet that is impinging on a rigid surface…
PIV Analysis of Ludwig Prandtl's Historic Flow Visualization Films
Christian Willert, Jürgen Kompenhans
Around 1930 Ludwig Prandtl and his colleagues O. Tietjens and W. Müller published two films with visualizations of flows around surface piercing obstacles to illustrate the unstead…
