Fluid-Structure Interactions

In line with the strategic objective of the University to carry out research that is more application oriented, the Research Centre for Fluid-Structure Interactions(FSI) was set up to perform research in the areas of fluid-structure interaction and its control. The objectives of FSI are to seek understanding of the fundamentals of fluid-structure interactions through experimental, numerical and theoretical studies and postgraduate training, and to apply such knowledge to resolve problems that are germane to Hong Kong and also China. Some of these problems are wind turbine aerodynamics, urban aerodynamic noise generated by modern appliances, construction site machines and pilings, structural design of tall buildings and large structures and biomedical applications. In particular, the emphasis is on the application aspects that require interdisciplinary investigations and have found fruitful results with significance in academic contribution and industrial application.

  • Introduction

    The Centre consists of staff members from Mechanical Engineering (ME), Building Services Engineering (BSE), and Electrical Engineering (EE) within PolyU and from Mechanical Engineering of HKU. Currently, there are GRF and other projects on-going within the Centre and they cover five areas;

    (1) Fundamentals of FSI and Its Control, (ii) Numerical code development, (iii) Application to 3-D structures, (iv) large-scale experiments, (v) small-scale experiments, (vi) air flow in human lungs and (vii) blood flow in micro vessels. Indeed, the Centre is carrying out its mission of doing research that is germane to Hong Kong.
