From designing cutting-edge aircraft to predicting aerodynamic performance, computational fluid dynamics (CFD) plays a pivotal role at all stages of the product lifecycle.
Since we were just in the wind tunnel last month (see our post here), we thought it would be fun to discuss how CFD can be used as a virtual wind tunnel. We’re big fans of real-world testing, but we think you get more value when you combine it with CFD-based predictions.
Below are a few of the advantages CFD has over a wind tunnel which make it a complementary tool.
◾ Upfront costs and schedule – Wind tunnel models are expensive and take time to build. These costs pay off once you are in the tunnel, but CFD has a much lower cost and lead time to seeing the first actionable results. Further, CFD allows teams to refine their early-stage concepts quickly, which means a design is much more mature by the time you enter the tunnel.
◾ Maximizing value – During a wind tunnel test campaign, time is a limited resource, and you want to extract the most value you can. Having a good set of CFD-based predictions allows the test engineers to focus on key strategic objectives or to troubleshoot unexpected results. One example is simulating full-scale Reynolds numbers in a low-speed (non-pressurized) tunnel. Full and model-scale CFD results can help the test crew employ techniques to approximate full-scale results.
While software and cloud computing have come a long way, you still need a team that knows how to interpret and deliver actionable results. TLG offers our customers world-class CFD services led by our in-house expert Dr. Peter Burns. Before joining TLG, Peter was the global aerospace technical specialist for Siemens PLM Software supporting their STAR-CCM+ software. Check out Peter and the rest of our leadership team, as well as a complete look at our engineering service offering, at https://lnkd.in/g9i2jwQ7.
