This project studies how fluid flows out from a small concentrated object into a second surrounding fluid. New solution methods will be provided, and new results about how these fluid flows evolve will be obtained. These are important problems with significance in modelling underwater explosions. They are also important in astrophysics, and will help explain the shapes of outflows from some stars or galaxies. The outcomes of the project will be a deeper mathematical understanding of which outflow shapes are stable, and under what circumstances they might become unstable. This will provide valuable information about galaxy shapes, and a new suite of computational methods for solving such problems.

这个项目研究流体如何从一个小的集中物体流出到第二个周围的流体中。将提供新的解决方法，并将获得关于这些流体流动如何演变的新结果。这些都是模拟水下爆炸的重要问题。它们在天体物理学中也很重要，并将有助于解释一些恒星或星系流出的形状。该项目的成果将是对哪些流出形状是稳定的，以及在什么情况下它们可能变得不稳定的更深入的数学理解。这将提供有关星系形状的宝贵信息，以及解决此类问题的一套新的计算方法。
