Experimental study of atmospheric pressure single-pulse nanosecond discharge in pin-to-pin configuration
Xingxing Wang, Adam Patel, Sally Bane +1
In this work, we present an experimental study of nanosecond high-voltage discharges in a pin-to-pin electrode configuration at atmospheric conditions operating in single-pulse mod…
Shock generated vorticity in spark discharges
Bhavini Singh, Lalit K. Rajendran, Pavlos P. Vlachos +1
Spark discharges induce a complex flow field consisting of a shock wave at early times (~ 1 s), a pair of vortex rings, and a hot gas kernel. The vortex rings entrain ambient g…
Meta-Uncertainty for Particle Image Velocimetry
Lalit K. Rajendran, Sayantan Bhattacharya, Sally P. M. Bane +1
Uncertainty quantification for Particle Image Velocimetry (PIV) is critical for comparing flow fields with Computational Fluid Dynamics (CFD) results, and model design and validati…
Filamentary Surface Plasma Discharge Flow Length and Time Scales
Lalit K. Rajendran, Bhavini Singh, Pavlos P. Vlachos +1
Nanosecond Surface Dielectric Barrier Discharge (ns-SDBDs) are a class of plasma actuators that utilize a high-voltage pulse of nanosecond duration between two surface-mounted elec…
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…
