PhD Studentship: Vibration enhancement of miscible flows
Engineering & the Environment
Location: Highfield Campus
Closing Date: Thursday 21 December 2017
Project Reference: NGCM-0096
Vibrations can be used to control heat/mass transfer, interface positions and phase separation. High-frequency vibrations may result in generation of average flows, formation of waves on interfaces, Faraday ripples, change of the body buoyancy conditions, etc. All these effects may be used to control and manage fluid flows in industrial applications.
For example, the oil-drilling companies show a growing interest in increasing the oil production with the help of oscillating (acoustic, vibrating, seismic, etc.) forcing to oil and gas fields. The increased interest to this technique is due to its low price, seeming simplicity of implementation, as well as due to the possibility to combine this technique with other methods, such as chemical, thermal, etc. It is assumed that vibrations may stabilise the oil/water interface, facilitate agglomeration of oil blobs making them more accessible for recovery, increase absorption rates for the miscible displacement
In the current project, we plan to investigate the effect of mechanical vibrations on miscible binary systems which saturate a porous medium. The pore-level description will be undertaken. The thermo- and hydrodynamic evolution of the binary mixture will be defined on the basis of the phase-field approach. We will focus on average effects of the high-frequency vibrations, which can be effectively analysed on the basis of the averaging approach, i.e. splitting the governing equations into two systems separately defining small-amplitude fluctuations and large-amplitude convective flows. This approach proved effective for description of enhancement/suppression of mixing by the action of mechanical vibrations and sound waves, description of fluid behaviour in microgravity conditions (a fluid system on board of the orbital space station), and others.
