Unseen—for the most part, unless rendered visible by dust or contrails—and always unwelcome, wake turbulence causes flight-path disruption at best, and fatal accidents when encountered at its worst. Pilots do what they can to avoid it, especially when on takeoff or landing, and controllers are tasked with helping us to steer clear. Still, we’re not always successful, and the price is paid in bent metal and lives lost.
Purdue University’s New Turbulence Model Predicts Complex Scenarios
Key Takeaways:
- Wake turbulence poses significant aviation hazards, but current complex simulation models for predicting it are computationally intensive and time-consuming.
- Purdue University researchers have developed a new "Coherent-vorticity-Preserving (CvP) Large-Eddy Simulation (LES)" model.
- This innovative model drastically reduces the computing power needed (1/10th to 1/100th) and speeds up the simulation of complex wake turbulence phenomena.
- The improved modeling has potential applications in designing aircraft that produce less hazardous wake turbulence and in developing various vehicle platforms.
