Developing Squeeze-Film Levitation


Project Description

Squeeze-film levitation (SFL) is a means of separation and non-contact movement of one surface over another, e.g. conveying and bearings. Consequently, there is no wear, almost no friction (except for fluid drag) and high accuracies of surface separation can be achieved. The load-carrying capacity is derived from the pressure within the fluid film, which can be generated by the relative motion, or squeeze motion, of the surfaces . We have built physical test rigs for SFL that are driven by piezoelectric actuators and recently developed a new working principle based on Poisson’s effect. We would now like to investigate meta-materials to enhance the SFL performance, as well as developing multiphysics models representing the material, fluid and actuator elements. Therefore, we would like to discuss these opportunities with suitable applicants.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: View Website. Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
