High-Resolution Calculations in Gas Dynamics

主要研究者承诺制定 最先进的软件包来计算不稳定的，化学的 复杂物体内部和周围的反应两相粘性流 形状 这种流体流动问题出现在空气动力学中， 例如在描述流过机翼的气流时 或者整架飞机或者导弹 另一个应用领域涉及研究和设计 内燃机、喷气发动机和涡轮机。 在这些应用中， 是可取的，但昂贵的计算。 拟开发的软件包旨在包括 精确和有效的数值算法， 并涵盖现有气体动力学程序的应用 和Navier-Stokes（流体流动）程序。

The principal investigator undertakes to develop a state-of-the-art software package to compute unsteady, chemically reacting, two-phase, viscous flows in and around objects of complex shape. Such fluid flow problems arise in aerodynamics, for example in describing airflow past wings or around entire planes or missiles. Another area of applications involves the study and design of internal-combustion engines, jet engines, and turbines. In each of these applications highly accurate simulations are desirable but expensive to calculate. The software package to be developed is intended to include accurate and efficient numerical algorithms, and to cover applications of existing gas dynamics programs and Navier-Stokes (fluid flow) programs.
