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並行算法來提高現代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:

通過GPU並行,全周非定常計算用於工程設計變得可能,將展示幾個代表性算例:

- Stall inception in axial fans (風扇失速非定常模擬)

- Integrated aircraft and propulsor simulations (飛發一體化仿真)

- Unsteady simulations of cooled turbines (渦輪冷卻非定常模擬)
