Effective Drift Velocity from Turbulent Transport by Vorticity
Hussein Aluie, Shikhar Rai, Hao Yin +5
We highlight the differing roles of vorticity and strain in the transport of coarse-grained scalars at length-scales larger than by smaller scale (subscale) turbulence. %sub…
Scaling of Turbulent Viscosity and Resistivity: Extracting a Scale-dependent Turbulent Magnetic Prandtl Number
Xin Bian, Jessica K. Shang, Eric G. Blackman +2
Turbulent viscosity and resistivity are perhaps the simplest models for turbulent transport of angular momentum and magnetic fields, respectively. The associated turbul…
Peristaltic pumping in sub-wavelength channels
Jessica K Shang, J Brennen Carr, Caroline D Cardinale +1
We apply the lubrication approximation to solve for the flow generated by a peristaltic traveling wave in a finite, planar channel, and examine the effect of channel length. Cerebr…
Peristaltic pumping in thin, non-axisymmetric, annular tubes
J. Brennen Carr, John H. Thomas, Jia Liu +1
Two-dimensional laminar flow of a viscous fluid induced by peristalsis due to a moving wall wave has been studied previously for a rectangular channel, a circular tube, and a conce…
Robust Principal Component Analysis for Modal Decomposition of Corrupt Fluid Flows
Isabel Scherl, Benjamin Strom, Jessica K. Shang +3
Modal analysis techniques are used to identify patterns and develop reduced-order models in a variety of fluid applications. However, experimentally acquired flow fields may be cor…
