Control of Transitions in Wakes and Swirling Flows. We will attack industrially-important problems in fluid mechanics by building new, and substantially enhancing existing, international collaborations between key complementary teams of internationally-recognised French and Australian researchers. Funding will support the exchange of 6 senior staff and 3 graduate students, which, in turn, will measurably benefit the research output of a further 20 graduate students and 7 post-doctoral fellows as ....Control of Transitions in Wakes and Swirling Flows. We will attack industrially-important problems in fluid mechanics by building new, and substantially enhancing existing, international collaborations between key complementary teams of internationally-recognised French and Australian researchers. Funding will support the exchange of 6 senior staff and 3 graduate students, which, in turn, will measurably benefit the research output of a further 20 graduate students and 7 post-doctoral fellows associated with closely-related projects. From the Australian perspective, the planned exchanges will bring new research expertise, knowledge and skills, which will be focussed on a diverse range of applications. Target industries (with existing collaborations) include Airbus and Dassault Aviation in Europe, and Aerosonde and Warman pumps in Australia. Read moreRead less
Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flow ....Rarefied hypervelocity separated flow in the transitional to continuum regimes. The transition regime for low-density flows is a no-man's-land between free-molecular and continuum flow, where the flow behaves differently to the assumptions typically used for modelling either flow type. Bird's direct Simulation Monte Carlo (DSMC) method is typically thought to be the best way of modelling these flows, but has not produced excellent agreement with previous experiments on low-density separated flows, due to computational limitations and lack of knowledge of the flow's internal energy. This proposal is a blind test of the best current DSMC codes against our experiments and a hypersonic continuum code, with the full internal energy state of the flow experimentally quantified for the first time.Read moreRead less
