CFD Visualization Helps Protect Integrity of Buildings, Bridges, and Ships

November 2010 When Adam Hapij, senior associate at the structural engineering firm Weidlinger Associates, recently visited his son’s kindergarten class, he tried to explain what he does in a way a 5-year-old could comprehend. In the end, he simply said, “I protect people.” Indeed, at its very core, Hapij’s job is to protect people. Since Weidlinger opened for business more than half a century ago, the company has designed all […]

CFD visualization helping researchers take the boom out of supersonic flight

Finding a solution may help lift FAA restrictions on supersonic flight in U.S. and open lucrative new markets for supersonic business travel Back in the 1970s, many corporate leaders envisioned a day when they might start their morning with a breakfast board meeting in New York, meet personally with city and state regulatory officials in Seattle that afternoon, and close their day with a business dinner for key customers in […]

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 […]

Plotting to Win the America’s Cup: Flow Dynamics of Racing Yachts

Contributed by Bruce Rosen Bay Simulations, Inc. The America’s Cup is the world’s oldest sporting trophy. Big, technology-laden racing yachts representing yacht clubs from countries around the world compete for the right to hold and defend this ornate piece of silver. Since 1992, the “IACC rule” has governed the size and other general characteristics of the roughly 70-foot yachts. Now a proposed 90-foot rule would give the naval architects more […]

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 […]
