Holographic shear rheology of viscoelastic fluids
Siddhartha Gupta, Siva A. Vanapalli
In this study, we report the use of digital holography microscopy (DHM) for 3D-resolved flow kinematics and shear rheometry of viscoelastic polymeric fluids. We computationally rec…

Origins of periodic and chaotic dynamics in microfluidic loop devices
Jeevan Maddala, Siva A. Vanapalli, Raghunathan Rengaswamy
Droplets moving in a microfluidic loop device exhibit both periodic and chaotic behaviors based on the inlet droplet spacing. We propose that the periodic behavior is an outcome of…
