An innovative wind power system primarily for urban environments. The project aims to develop a novel rotor vane array wind power system that can be used as a roof fence or balcony on existing or new buildings. Traditional wind turbines cannot fully realise the potential of excellent wind speed in tall buildings because of space efficiency, visual impact, and danger or noise issues. The system to be developed in the project incorporates advanced active flow control that addresses these issues. T ....An innovative wind power system primarily for urban environments.

Mechanisms of sound absorption at the nanoscale. Understanding the interaction of sound with nanoscale structures will guide the creation of novel carbon nanotube materials, optimised for sound absorption, which have potential application anywhere that noise exists and needs to be attenuated. Fuel savings from reduced drag and weight in applications such as jet aircraft engines are also expected.

Summary
Resolving the mechanics of wall-mounted finite airfoil noise production. Noise from air transportation and wind turbines is a rapidly growing component of environmental noise pollution that must be reduced to improve public health and well-being. A submarine must also have a low acoustic signature to ensure its stealthiness. The common source of noise generation among these technologies is the airfoil, yet we do not understand how they create noise in real, complex environments. This project aim ....Resolving the mechanics of wall-mounted finite airfoil noise production. Noise from air transportation and wind turbines is a rapidly growing component of environmental noise pollution that must be reduced to improve public health and well-being. A submarine must also have a low acoustic signature to ensure its stealthiness. The common source of noise generation among these technologies is the airfoil, yet we do not understand how they create noise in real, complex environments. This project aims to understand how fluid flow interacts with a wall-mounted finite airfoil to produce sound. The project aims to identify the noise producing physics via a novel wind tunnel experiment and numerical study. This enhanced understanding will create better airfoil noise prediction and control strategies in the future.Read moreRead less

Comfort and ergonomics: Innovative seating solutions for commercial vehicles. This project aims to develop a 6-degree-of-freedom seating system for commercial vehicles, including heavy duty trucks and mobile machinery, to reduce unwanted multiple directional vibrations to the driver’s body. Long-term exposure to vibrations from uneven road surfaces, vibrating tools, and vibrating machinery affects driver comfort, fatigue and safety, and can also cause neck and shoulder pain, lower back injuries, and spinal injuries. The expected outcome of the project is a comfortable and ergonomic seating system that, agriculture, transportation, mining and construction vehicles, both in Australia and internationally, can widely use.Read moreRead less

This project aims to improve forklift design to reduce the vibration experienced by forklift drivers. Research consistently links forklift driving with a high incidence of back pain and musculoskeletal injuries through exposure to hand, arm and whole-body vibrations that are caused by the rigid passive suspension in traditional forklifts, which cannot properly absorb vibration stemming from deviations in driving surfaces, changes in mass, or common loading, lifting and unloading actions. The project aims to draw on the research team’s expertise in magnetorheological technology to develop and evaluate a new tuneable integrated semi-active wheel and chassis and seat suspension system that can vary damping and stiffness to control mass uncertainty and vibration.Read moreRead less
