Periodic pressure oscillations applied to the opening of closed containers packed with small beads or granular material result in an enhanced washout of undesired gases from those containers. The amplitude of oscillation pressures need not be higher

The temporal and spatial characteristics of thermal pulses travelling in conduits of finite wall conductivity are studied using a multiple time scale expansion. Values for the effective dispersion coefficient of these pulses for parabolic laminar flo

Mean speeds of laminar flow in tubes are determined non-invasively using thermocouple measurements of thermal pulse speeds. Such pulses are shown to travel at a unique submean low velocity which is directly proportional to the volume flow rate. The r

Small amplitude oscillations have been shown to raise the diffusional flux in cylindrical tubes by orders of magnitude. The flux is especially high when the oscillation frequency is tuned to the size of the capillaries and to the properties of the ga

The problem of Enhanced Axial Heat Transfer (EAHT) in oscillatory pipe flow has been numerically studied. Time-dependent velocity and temperature profiles and Lagrangian and tidal displacements at various Wormersley numbers are obtained. The enhanced

We present a method for separating gases and solutes by oscillating the fluid column. The process is based on augmented diffusion and is akin to Taylor dispersion. The augmentation of the flux, as compared to simple molecular diffusion, is 3 orders o
