The experimental information gained from measurements provided by this infrastructure will lead to significant advances in understanding turbulent flows and the dynamics of solid structures, which will impact a broad range of engineering and geophysical fields. Some specific examples include the development of efficient turbulence control strategies for the reduction of skin-friction drag and improved combustion processes, resulting in not only better fuel efficiency for vehicles but also reduced CO2 and pollutant emissions. Significant advances can also be made in understanding the dispersion of pollutants in the atmosphere, wind turbine design and the development of lighter and stronger intelligent materials with improved fatigue life.Read moreRead less
Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels ....Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels, reducing material and manufacturing costs without compromise to safety and performance - an immense benefit for the myriad engineered products or structures that feature flow over a deformable surface.

Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective o ....Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective of reducing drag by adhering a compliant skin to the surface. While the correct choice of compliance relies upon understanding very complex flow-structure dynamics, the resulting technology is simple, robust and has low capital and maintenance costs. Clearly, drag reduction reduces fuel costs and lower fuel consumption is environmentally beneficial. Read moreRead less

Ferroelectric single crystals were invented 5 years ago, and they possess many superior properties compared to conventional piezoelectric materials, particularly the induced strain up to 1.5%, an order higher than conventional materials. This project aims to poineer the application of these new and powerful smart materials as actuators and sensors to shape control of smart structures. The expected outcomes are (a) a new constitutive theory for the non-linear behaviour of ferroelectric single crystals; (b) a novel definition and formulation for the shape control problem; and (c) an innovative theoretical framework for design optimization of shape control of smart structures using ferroelectric single crystals.Read moreRead less
