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.

该项目旨在更好地预测与现有的经验模型相比，预测磁动力动力学的湍流。在各种工程，地球物理和天体物理流动中，电导流体维持磁场的高速流中的湍流。然而，对磁流动力流的研究仅限于缓慢的流动，并且结果将结果应用于实际问题。该项目旨在使用与管理方程式的高速极限一致的理论和数值工具，改善未来产生能源技术中的磁性流动力流量控制。更有效的发电机可以通过更少的全球变暖气体排放量来改善澳大利亚未来的能源供应。
