The project aims to better predict magneto-hydrodynamic turbulence than existing empirical models. Turbulence in high-speed flows of electrically conductive fluid sustains magnetic fields in various engineering, geophysical, and astrophysical flows. However, investigations into magneto-hydrodynamic flows have been limited to slow flows, and the application of the results to the actual problems hindered. This project aims to improve magneto-hydrodynamic flow control in future energy-generating technology, using theoretical and numerical tools that are mathematically consistent with the high-speed limit of the governing equations. More efficient electric generators could improve Australia’s future energy supply with fewer emissions of global warming gases.

该项目旨在比现有的经验模型更好地预测磁流体动力学湍流。导电流体高速流动中的湍流维持各种工程、地球物理和天体物理流动中的磁场。然而，磁流体动力学流动的研究一直局限于缓慢的流动，和实际问题的应用结果受到阻碍。该项目旨在改善未来能源发电技术中的磁流体动力学流量控制，使用与控制方程的高速极限在数学上一致的理论和数值工具。更高效的发电机可以改善澳大利亚未来的能源供应，减少全球变暖气体的排放。
