To Seal or Not To Seal
Javad Eshraghi, Sunghwan Jung, Pavlos P. Vlachos
When an object impacts the free surface of a liquid, it ejects a splash curtain upwards and creates an air cavity below the free surface. As the object descends into the liquid, th…
Uncertainty-based pressure field reconstruction from PIV/PTV flow measurements with generalized least-squares
Jiacheng Zhang, Sayantan Bhattacharya, Pavlos P. Vlachos
A novel uncertainty-based pressure reconstruction method is proposed to evaluate the instantaneous pressure fields from velocity fields measured using particle image velocimetry (P…
Volumetric Particle Tracking Velocimetry (PTV) Uncertainty Quantification
Sayantan Bhattacharya, Pavlos P. Vlachos
We introduce the first comprehensive approach to determine the uncertainty in volumetric Particle Tracking Velocimetry (PTV) measurements. Volumetric PTV is a state-of-the-art non-…
Uncertainty amplification due to density/refractive-index gradients in volumetric PTV and BOS experiments
Lalit K. Rajendran, Sally P. M. Bane, Pavlos P. Vlachos
We theoretically analyze the effect of density/refractive-index gradients on the measurement precision of Volumetric Particle Tracking Velocimetry (V-PTV) and Background Oriented S…
Two Regime Cooling in Flow Induced by a Spark Discharge
Bhavini Singh, Lalit Rajendran, Pavlos P Vlachos +1
The cooling process associated with the flow induced by a spark plasma discharge generated between a pair of electrodes is measured using stereoscopic particle image velocimetry (S…
Uncertainty Quantification in density estimation from Background Oriented Schlieren (BOS) measurements
Lalit K. Rajendran, Jiacheng Zhang, Sayantan Bhattacharya +2
We present an uncertainty quantification methodology for density estimation from Background Oriented Schlieren (BOS) measurements, in order to provide local, instantaneous, a-poste…
