Wind loads have a great impact on the viability of a structure, but through testing in wind tunnel studies, it is possible to optimise the design to ensure that structures can withstand the wind loads. The challenge is that traditional wind tunnel tests (using physical wind tunnels) are performed very late in the design process and that means that any design changes or savings found in the test requires a lot of re-work. This can be a time-consuming and expensive processes. And quite simply, there is only a limited number of wind tunnels available for testing, which hinders flexibility and induces slower responses. Every time you need to test a potential design change – lets say, for example, that you wish to test whether a building design works better with rounded corners than with sharp edges – it means having to build an all-new model, and that can be a cumbersome process. Moreover, testing scaling effect and smaller features of the design is challenging in a physical wind tunnel. At Ramboll, we have experienced these challenges first-hand, on complex building projects such as Bella Sky and Carlsberg City in Copenhagen. That is why we are developing a new digital alternative, using Computational Fluid Dynamics (CFD). This virtual approach has less restrictions, provides superior visualisation features and creates key insights. The digital alternative: a multi-study approach We call it the digital wind tunnel. The approach can allow you to simulate, visualise and get accurate predictions of wind loading on the structure(s) in question – in a risk-free and flexible virtual environment. The digital wind tunnel model makes it is possible to easily test different design possibilities, so you end up with the optimal solution.
