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…

Competitive Double Diffusive Convection in a Kelvin–Voigt Fluid of Order One
We present a model for convection in a Kelvin–Voigt fluid of order one when the layer is heated from below and simultaneously salted from below, a problem of competitive double diffusion since

We present numerical techniques for calculating instability thresholds in a model for thermal convection in a complex viscoelastic fluid of Kelvin–Voigt type. The theory presented is valid for
Thermosolutal Convection with a Navier–Stokes–Voigt Fluid
We present a model for convection in a Navier–Stokes–Voigt fluid when the layer is heated from below and simultaneously salted from below, the thermosolutal convection problem. Instability thresholds


Viscoelastic squeeze-film flows – Maxwell fluids
An exact solution for the squeeze-film motion in an upper convected Maxwell fluid is given for both the plane and axisymmetric cases. Inertia and viseoelastic effects are included, and it is shown
Tuning effect in enhanced gas dispersion under oscillatory conditions
It is shown that the effective axial dispersion coefficient for partially mixed gases confined to cylindrical tubes and subjected to sinusoidal oscillations reaches a maximum, at a constant
Dispersion in flows with streamwise variations of mean velocity: Radial flow
The familiar example of Taylor dispersion in pipe flow is extended to the case of laminar flows with velocity variations in the streamwise direction. The effective dispersivity is shown to depend on

Taylor dispersion in the presence of cross flow and interfacial mass transfer
A solute flowing in a pressure-driven channel flow experiences an enhanced effective axial dispersion coefficient due to the transverse velocity gradients. An investigation shows how this phenomenon,

A magnetorheological fluid squeeze-mode isolator is proposed to improve the vibration isolation performance of a subway floating slab track system. However, it is difficult to carry out the test for
