Research Initiation Award: Adaptive Pseudospectral Method for Viscous Fluid Flows

根据一项研究启动奖，计算流体动力学（CFD）将用于可压缩粘性流动。利用自适应算法的伪谱方法的准确性和效率将通过一维和二维纳维尔斯托克斯方程进行测试。在二维中，气流将是经过一个有气流分离的后台阶的气流。气流将是超音速的。这项研究将提高计算的可预测性，以及对工程系统上和通过的具有摩擦的超高速流动的物理理解。

Under a Research Initiation Award, Computational Fluid Dynamics (CFD) will be carried out for compressible viscous flows. The accuracy and efficiency of a pseudospectral method utilizing an adaptive algorithm will be tested with the one- and two- dimensional Navier Stokes equation. In two dimensions, the flow will be that over a rearward step with flow separation. The flow will be supersonic. The research will enhance the computational predictability, and physical understanding, of very high speed flows with friction over and through engineering systems.
