Studying the Complex Flow Physics of Dragonfly Flight
Contributed by Dr. Haibo Dong Manager, Wright State University For the first time in history, researchers have been able to create a detailed 3D numerical simulation of a dragonfly in free flight. On the left is a high-speed movie of a dragonfly taking off. The black spots on the wing are 0.5mm ink markers that help track exact wing positions when creating the 3D shapes using films shot from different […]
Using Visualization for Faster Understanding of Noise Issues
Contributed by Shen Heping, Software Development Manager, Hong Yuan Tech. Cars that ride more quietly. Higher-quality acoustics in auditoriums. Aircraft that meet or noise pollution regulations. These are just a few examples of how scientists and engineers can develop more comfortable, enjoyable, or environmentally-sound products by studying the source and distribution of noise. The ability to actually see the noise distribution or what’s going on around the noise source helps […]
Understanding the Flow Physics of Coolants
Using advanced software tools to study the physics of airflow and how it impacts the performance of aircraft engines. […]
Tecplot helps utility researchers visualize magnetic fields
Contributed by Sylvain Gravel Hydro-Québec The Challenge: Accurately Visualizing Magnetic Flux Density In working with electrical power production and distribution, a key problem faced is being able to see the unseen – in other words, how does one view invisible electrical and magnetic forces at play? Hydro-Québec needed to be able to see magnetic flux density near a distribution power line, which is essentially understanding the power flow in the […]
Advanced Simulation Code Unveils the Mystery of Acoustic Waves
Contributed by Dr. Baki Farouk Drexel University Problem Statement: Numerical simulations of the standing wave and acoustic streaming in a resonator filled with nitrogen (Fig. 1) are presented. The initial gas pressure in the resonator is 1 atm (101 KPa), and temperature is 300 K. The vibrational frequency of the left wall is chosen as f = 20 kHz. The corresponding wavelength of the sound wave at this frequency is […]
