Investigation of methane-fueled rotating detonation combustor exhaust flow field via time-resolved particle image velocimetry
… with its operation cycles as compared to traditional constant pressure combustion systems. However, significant scientific exploration must still be conducted to maximize the potential benefits of RDCs, including the implementation of proper flow conditioning devices downstream of the …

Analysis of Ship Airwakes Using Modal Decomposition
… time-resolved particle image velocimetry (TR-PIV) measurements were made at six different crosswise planes over the flight deck region of the ship model, with and without the effect of a simulated atmospheric boundary layer (ABL).</p> <p>Spatiotemporal analyses of the TR-PIV …

Mean Flow Characteristics and Turbulent Structures of Turbulent Boundary Layers in Varying Pressure Gradients and Reynolds Numbers
… wall-normal, stereoscopic particle image velocimetry (TR-PIV) measurements were made. The TR-PIV data was acquired at a chord-based Reynolds number of 1.2 million, 2 million, and 3.5 million, at a sampling rate of 1 kHz, in two different camera configurations. The boundary layer pressure …

Contributions to the Understanding of Ship Airwakes Using Advanced Flow Diagnostic Techniques
… unsteady aerodynamic flows produced by the superstructure of a ship, which is referred to as an airwake. This problem is relevant and important because the turbulent airwake significantly and adversely affects the ability for rotorcraft to operate safely from the decks of Navy ships. To this end, …

Data Analysis of an Unsteady Cavitating Flow on a Venturi-type Profile
… data obtained from planar Particle Image Velocimetry (PIV). Three data-driven techniques, Proper Orthogonal Decomposition (POD), Dynamic Mode Decomposition (DMD), and Clustered-based Reduced Order Modeling (CROM), are applied to the snapshots of the fluctuating component of velocity to investigate …
