# Time-averaged transport in oscillatory squeeze flow of a viscoelastic fluid

@article{Yang2020TimeaveragedTI, title={Time-averaged transport in oscillatory squeeze flow of a viscoelastic fluid}, author={Rui Yang and Ivan C. Christov and Ian M. Griffiths and Guy Z. Ramon}, journal={Physical Review Fluids}, year={2020} }

Periodically-driven flows are known to generate non-zero, time-averaged fluxes of heat or solute species, due to the interactions of out-of-phase velocity and temperature/concentration fields, respectively. Herein, we investigate such transport (a form of the well-known Taylor--Aris dispersion) in the gap between two parallel plates, one of which oscillates vertically, generating a time-periodic squeeze flow of either a newtonian or Maxwellian fluid. Using the method of multiple time-scale…
