Vortex rings drive entrainment and cooling in flow induced by a spark discharge
Bhavini Singh, Lalit K. Rajendran, Jiacheng Zhang +2
Spark plasma discharges induce vortex rings and a hot gas kernel. We develop a model to describe the late stage of the spark induced flow and the role of the vortex rings in the en…
Weighted Least Squares (WLS) Density Integration for Background Oriented Schlieren (BOS)
Lalit Rajendran, Jiacheng Zhang, Sally Bane +1
We propose an improved density integration methodology for Background Oriented Schlieren (BOS) measurements that overcomes the noise sensitivity of the commonly used Poisson solver…
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…
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…
4D-Flow MRI Pressure Estimation Using Velocity Measurement-Error based Weighted Least-Squares
Jiacheng Zhang, Melissa C. Brindise, Sean Rothenberger +5
This work introduces a 4D-flow magnetic resonance imaging (MRI) pressure reconstruction method which employs weighted least-squares (WLS) for pressure integration. Pressure gradien…
