摘要

目前的研究旨在使用计算风工程工具获得充气膜结构上的平均压力分布。稳态分析采用雷诺平均Navier-Stokes方程和标准湍流模型。将压力系数与以往的实验结果进行了比较，验证了数值解的正确性。在将数值结果与风洞试验进行比较时，在临界流分离点附近发现了显著的误差。然而，这些误差是局部的，数值方法在湍流运动影响较小的区域提供了准确的结果。一般来说，数值解提供了压力系数场的良好近似。

Computational wind analysis of an open air-inflated membrane structure

The current research aimed to obtain mean pressure distribution over an air-inflated membrane structure using Computational Wind Engineering tools. The steady-state analysis applied the Reynolds-Averaged Navier-Stokes equations with the standard turbulence model. The pressure coefficients were compared with former experimental results to validate the numerical solution. Significant errors were detected close to the critical flow separation points when comparing the numerical results with the wind tunnel tests. However, these errors are local, and the numerical methodology provides accurate results in those areas with minor turbulence motion influence. In general, the numerical solution provided good approximation of the pressure coefficient fields.
