Time-dependent dynamic, creep and shrinkage response of curved structural members. This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed.

This project concerns curved structural members, such as bridge beams, that are subjected to dynamic excitation and to concrete shrinkage and creep. Hitherto, unified formulations for the structural behaviour of these members have not been properly developed. The proposal seeks to build on a previous ARC DP of the investigator that produces significant results for static loading, by developing a sophisticated methodology to handle non-static dynamic loading and for shrinkage and creep. It will develop advanced mathematical tools to enable the safe and efficient design of a multiplicity of structures that is of benefit to on and offshore Australian technology.Read moreRead less

The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries. Unlike the previous CFD studies which have been made on the assumptions that the flow is steady and decoupled from the heat transfer calculations in this Project the fully coupled problem will be solved, in which unsteady flows are allowed to occur over a dimpled surfaces. As a result we will be able to more accurately determine the resultant effects on the pressure drop and heat transfer. Read moreRead less

Gears are widely used in industry and transport. This project aims to integrate the two main methods of gear condition monitoring, vibration and oil analysis, and perform model-based wear prediction with the tribology and dynamic models continually updated on the basis of measured wear debris and vibration. New signal processing tools should allow estimation of relatively weak friction forces, previously neglected, as an important prognostic tool. This would allow detailed root cause analysis and prediction of remaining useful life. Improvements in gear prognosis would have safety and economic benefits by eliminating unforeseen catastrophic failures and optimising maintenance schedules.Read moreRead less

This project explores several methods for enhancing the heat transfer performance of mechanically bonded finned tube heat exchangers. The methods would be analysed experimentally, and using finite elements, numerically. Any increase in heat transfer efficiency would contribute to the conservation of energy, and therefore, of natural resources. An improved design of heat exchangers would give a definite competitive edge to the Australian manufacturer. An equally significant outcome would be the training of a research person in industry-related research and skilled both in experimental and numerical procedures.Read moreRead less
Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using ai ....Modelling the Transient Effects in Dense Phase Gas-Solids Flow in Pipelines. Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using air as the motive force. However, the cost of poor design and the inaccurate prediction of system performance adversely affect the efficiency of many industries. Improvements to the accuracy of gas-solid flow modeling particularly for low velocity dense phase systems will have a direct impact on manufacturing efficiency.Read moreRead less
