Abstract:

摘要:

Taking advantage of highly parallel processors such as Graphics Processing Units is the key to unlocking high performance in modern CFD solvers. In this talk, this opportunity is explored in the context of Turbostream, a highly scalable hybrid structured/unstructured CFD solver for flows in turbomachines.

利用高效GPU并行算法来提高现代CFD求解器效率和性能。

Using GPUs, high-fidelity methods such as unsteady full-annulus simulations can now be used as part of the routine turbomachinery design process for the first time. Several examples of such simulations which have been previously published are presented, including:

通过GPU并行,全周非定常计算用于工程设计变得可能,将展示几个代表性算例:

- Stall inception in axial fans(风扇失速非定常模拟)

- Integrated aircraft and propulsor simulations(飞发一体化仿真)

- Unsteady simulations of cooled turbines(涡轮冷却非定常模拟)
