摘要:

虚拟风洞是虚拟现实技术和CFD技术在飞机设计和改型中的应用。本文分析了虚拟风洞的工作流程,并针对国内相关硬件水平提出了一个分布式虚拟风洞结构设计方案。在此结构上,完成了负载的合理分配。最后,以一个典型CFD应用为例分析了分布式虚拟风洞系统的硬件要求和性能。

Abstract:

Virtual Wind Tunnel is the application of VR and CFD technology in airplane design. This paper first analyzed the work process of VWT. Then a distributed Virtual Wind Tunnel system structure was proposed based on our currently available hardware and the workload was distributed properly. Finally, with a typical CFD application as an example, the hardware necessities and performance of the VWT were fully analyzed.

Key words: CFD, visualization, virtual wind tunnel, distributed, workload distribution
