Studying the Complex Flow Physics of Dragonfly Flight
Contributed by Dr. Haibo Dong Manager, Wright State University, http://www.wright.edu/ 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 […]
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 […]

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 […]
iReservoir Optimizes Oil and Gas Recovery Methods
The Challenge: Understanding Complex Subsurface Fluid Interactions Before optimization of recovery methods for sub-surface oil and gas reservoirs can be obtained, a thorough understanding of the reservoir is required. These reservoirs have many complex structural, geological, and fluid characteristics that are impossible to fully understand using actual measurements and physical testing. Static and dynamic computer-based models and an arsenal of high-tech, computational tools are required to simulate reservoir performance and […]
