The Wind Technology Society's (WTG) guideline for wind tunnel testing has long served as a benchmark in wind engineering. Recognizing the growing relevance of Computational Fluid Dynamics (CFD) methods, a dedicated guideline for these numerical approaches has been introduced. This new guideline aligns with Eurocode EN 1991-1-4, which allows the use of both experimental and numerical techniques, provided they undergo rigorous validation. Consequently, the core emphasis of the new guideline is on validation.
Eurocode provisions permit the use of wind tunnel testing and validated numerical methods, ensuring that wind and structural modeling are accurate. While the initial validation process requires meticulous attention, the effort can be streamlined for similar future projects. It remains the user's responsibility to ensure compliance, rather than the software developer's.
The WTG guideline is designed to offer comprehensive guidance and practical support to developers and clients conducting CFD simulations in wind engineering. This handbook aims to deliver a clear explanation of the key elements of the WTG guideline for practicing engineers and demonstrates practical applications using RWIND through relevant examples.
