A novel method to improve the accuracy of pressure field estimation from time-resolved Particle Image Velocimetry data is proposed. This generates several new time-series velocity by propagating in time original one using an advection-based model, which assumes that small-scale turbulence advected large-scale motions. Then smoothing performed at corresponding positions across all generated time-series. The process repeated through iterative scheme. proposed technique smears out spatial noise...
The most explored path to obtain pressure fields from Particle Image Velocimetry (PIV) data roots its basis on accurate measurement of instantaneous velocity and their corresponding time derivatives. This requires time-resolved measurements, which are often difficult achieve due hardware limitations expensive implement. In alternative, snapshot PIV experiments more affordable but require enforcing physical constraints (e.g. Taylor's hypothesis) extract the derivative field. this work, we...
This study focuses on an active strategy for unsteady-load control by means of a trailing-edge flap. Experiments 2D pitching and heaving NACA 0018 airfoil with actuated flap are performed at reduced frequency in free-stream flow . The model is equipped 24 differential pressure transducers to provide the time-resolved distribution difference between suction sides. Results show that significantly decreases magnitude unsteady loads. A order effect loads proposed. estimated adding contribution...
Abstract This work presents an experimental setup for acquiring synchronized wall and flow field measurements in a turbulent boundary layer (TBL). Instantaneous of the convective heat transfer distribution at are carried out simultaneously, using wall-parallel planar particle image velocimetry infrared thermography. A low-thermal-inertia heated-thin-foil sensor is embedded beneath TBL to measure temperature maps with enough temporal resolution. The unsteady energy balance heated foil can be...
"This study investigates the feasibility of using neuromorphic event-based vision (EBV) camera for low-order modelling, a key enabler real-time flow control. A synchronized experiment with simultaneous Event Based Image Velocimetry (EBIV) and Particle (PIV) is performed on submerged water jet at Re = 2600. Flow statistics, spectral content, reduced-order modeling capabilities Proper Orthogonal Decomposition (POD) are assessed. Velocity fields computed via standard PIV processing compared...
The convective heat transfer enhancement in a turbulent boundary layer (TBL) employing pulsed, slot jet crossflow is investigated experimentally. A parametric study on actuation frequencies and duty cycles performed. actuator flush-mounted that injects fluid into well-behaved zero-pressure-gradient TBL over flat plate. heated-thin-foil sensor measures the time-averaged coefficient downstream of location flow field characterised by means Particle Image Velocimetry. results show both...
Ensemble Particle Tracking Velocimetry (EPTV) is a method to extract high-resolution statistical information on flow fields from Image (PIV) images. The process based tracking particles and extracting the velocity probability distribution functions of image ensemble in averaging-regions deemed contain sufficient number of particle pairs/tracks. The size averaging regions depends particle density the number snapshots. An automatic adaptive variation PTV presented to further push spatial...

The setup consists heaving pitching at moderate Reynolds number ([Formula: see text]), Strouhal St = 0.1. aim is to assess accuracy two-dimensional direct simulations predicting aerodynamic forces configuration, which nominally but verge three-dimensionality. assessment carried out with experiments, including field force measurements particle image velocimetry load cell....
This paper reports a comparison between wind-tunnel measurements and numerical simulations to assess the capabilities of Reynolds-Averaged Navier-Stokes models estimate wind load over solar-panel arrays. The free airstream impinging on arrays creates complex separated flow at large Reynolds number, which is severely challenging for current models. compared in this article are k-ϵ, Shear-Stress Transport k-ω, transition Shear Model. Particle Image Velocimetry performed investigate mean...
This paper discusses the integration of an air collector and dissipation cavity into a closed anechoic chamber for jet noise studies. Having issued directly in introduces recirculation effects, which influence plume, producing different flow compared to free emitted open environment. The implementation aims redirect, dissipate extract effectively airflow downstream region chamber. fact being closed-section facility provokes recirculation, influences potential core plume. However, any...
