Postdoc: HPC Methods for Coupled Fluid/Structure/Control Problems

气动、结构和控制系统的一体化设计对新型商用飞机的研制是必不可少的。 通过数值模拟验证这种设计需要同时求解适当耦合的流体、结构和控制运动方程。因此，飞机整体设计的数值模拟是计算密集型的。 他们建议开发高性能的计算方法来解决这些具有挑战性的问题，并将其应用于斜飞翼（OFW）和公司超音速运输机（CST）的调查。 OFW是一种最佳的空气动力学和结构组合，具有速度快、尺寸大的特点，因此引起了人们极大的兴趣。 此外，它的控制可能是最具挑战性的。 另一方面，CST可能是协和式飞机之后建造的第一架民用超音速飞机。 虽然CST的控制可以预期比OFW的控制不那么困难，但它仍然需要相当多的计算资源。 拟议的研究是多学科的，包括几个组成部分：计算流体力学，计算结构力学，动力学和主动控制，以及应用数学，数值分析，计算机科学和并行处理。 拟议的研究将主要由Pei Li博士在Farhat教授的监督下，在Seebass教授和Lawrence教授的协助下进行。 将提供计算方法和并行处理方面的必要培训以及所需的计算机资源。

The integrated design of aerodynamic, structural, and control systems is essential to the development of new commercial aircraft. The validation of such a design by numerical simulations requires solving simultaneously the appropriately coupled fluid, structural, and control equations of motion. Consequently, the numerical simulation of an integrated aircraft design is computationally intensive. They propose to develop high performance computational methodologies for addressing such challenging problems, and apply them to the investigation of an Oblique Flying Wing (OFW) and a Corporate Supersonic Transport (CST). The OFW is of great interest because it corresponds to an optimum aerodynamic and structural combination, and offers speed and large size. Moreover its control is likely to be most challenging. On the other hand, the CST is perhaps the first civilian supersonic aircraft that will be built after the Concorde. While the control of the CST can be expected to be less difficult than that of the OFW, it will still demand considerable computational resources. The proposed research is multidisciplinary and includes several components: computational fluid dynamics, computational structural mechanics, dynamics and active control, as well as applied mathematics, numerical analysis, computer science, and parallel processing. The proposed research will be carried out primarily by Dr. Pei Li, under the supervision of Professor Farhat, with the assistance of Professors Seebass and Lawrence. The necessary training in computational methods and parallel processing, and the needed computer resources will be provided.
