Today’s low-cost computational resources have fundamentally changed the way we approach unsteady CFD analysis. These dramatic changes have seen the shift from steady-state analysis to the use of unsteady or transient simulations. Unsteady CFD allows engineers and scientists to study moving machinery and turbulence flows over a period of time under varying conditions. A look at vertical wind turbine design shows how Tecplot, Inc. is working to improve quantitative capabilities and qualitative analysis for safe, cost-effective, and accurate engineering design.
Unsteady CFD Requires Both Qualitative and Quantitative Understanding
As U.S. funding for ‘green’ power increases, wind turbine size is decreasing and going vertical. Small, quiet, easy to install, ‘green’ micro power devices have the potential to lower our carbon footprint, and, perhaps more significantly, bring power to to many hard-to-reach rural areas.
Exploring these new turbine designs is possible because engineers can now choose the independent tools best suited for their unsteady CFD analysis. Automating the simulation process helps designers analyze, for example, vortex shedding as a function of time or wind speed, and then make subtle changes in blade shape. Analyzing hundreds of simulations with tools tailored for the specific task results in more efficient designs—in this case wind turbines with higher torque and increased efficiency.
Tecplot 360 Animation Shows Dramatically Visible Results
While the growth of computational power led to unsteady CFD analysis, that alone does not guarantee a way for engineers to use and organize all the qualitative and quantitative data produced from their test runs. Watch Tecplot 360 deliver an integrated way to view the simulation and the data.
Tecplot 360 Optimizes the Engineers Time to Understanding
Whether you are working with ten solutions or hundreds, engineers need a simple way to organize their unsteady CFD data, turn it into animations, and seamlessly use post-processing to evaluate their work. Tecplot 360 2011 makes it easy for engineers to simultaneously look at visualizations and the underlying data in one integrated screen. You can quickly plot and animate all your data exactly the way you want it, then rearrange your layouts to communicate your results.
