Using a File Format that Loads CFD Data 10 Times Faster

The Challenge Jared Gudenkauf is a CFD engineer (Jacobs engineering contractor) working in the fluid dynamics branch (ER42) of NASA Marshall Space Flight center in Huntsville, Alabama. Jared runs CFD in support of the Space Launch System (SLS), Mars Ascent Vehicle, and “Lunar Flashlight” Lunar Orbiter. His calculations for the SLS Ignition Over-Pressure/Sound Suppression water system involve two-phase flows. Jared’s main CFD code is Loci/CHEM, which he runs on the […]

Aerion Corp. Developing New Supersonic Business Jet

CFD simulations key technique for reducing airframe’s aerodynamic drag “It’s all about increased efficiency,” explained Spencer Fugal when describing the overall benefit his organization derives from its use of Tecplot Chorus. “The software allows us to automate the process of simultaneously comparing the results of different CFD simulations. This greatly accelerates the pace at which we can identify anomalies and validate or disprove our CFD results.” Fugal, a former Boeing […]

CFD Simulations Help Design Cleaner Gas Turbine Engines

Research institute in Germany uses CFD simulations to help design cleaner gas turbine engines. Climate change caused, in part, by heavy airplane traffic is a global concern. In Germany, a group of researchers at the University of Stuttgart’s Institute of Aerospace Thermodynamics is working on a project funded by the German Research Foundation and the Research Association for Combustion Engines to improve modern gas turbines by changing the geometry of […]

Supersonic Unmanned Aerial Vehicles Close To Becoming Reality

Researchers at University of Colorado developing supersonic UAV that’s fast, economical, and fuel-efficient It’s small. It’s fuel-efficient. It’s reasonably priced. And it’s fast. Supersonic fast. It is an unmanned aerial vehicle (UAV) that will fly at speeds approaching Mach 1.4 and faster than anything in the sub-50 kg vehicle category today, using an engine two to four times more efficient than any other in its class. Under development by researchers […]

Overcoming the curse of dimensionality in hypersonic design

Tecplot Chorus helps University of Colorado researchers demonstrate method for kriging surrogate models to increase accuracy of low fidelity results by an order of magnitude. May 2012 The decades-old quest to develop hypersonic vehicles powered by airbreathing1 engines for space exploration, defense, and air travel has yielded some promising results. Yet the goal of developing viable designs for commercial use remains elusive. Designing manned and unmanned vehicles for hypersonic speeds—anything […]

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 […]

Tecplot Focus Helps Probe Manufacturer Showcase Technology and Sell Products

Contributed by Jonathan Binns Aeroprobe The Researchers Trying to sell potential customers on the benefits of complex multi-hole probe technology would be nearly impossible without being able to provide a first-hand demonstration of the probe’s capability to generate quality data. For Aeroprobe Corp., that’s where Tecplot Focus software comes into the picture. The Blacksburg, VA-based manufacturer of multi-hole probe instrumentation uses Tecplot Focus visualization software to prove its products’ capabilities […]
