A new case study by Brazilian Tecplot distributor ATS describes their “meticulous analysis” of the aerodynamics of the entire car, including the tradeoffs between top speed, downforce for cornering performance and braking – key components to lower lap times. […]
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 […]
Paul Ferlemann is an aeronautical engineer and researcher at the Hypersonic Airbreathing Propulsion Branch (HAPB) of the NASA Langley Research Center. The HAPB performs research to develop advanced technology for hypersonic airbreathing propulsion systems for aerospace vehicles. The focus is on airframe-integrated engine concepts having high performance over a wide range of flight Mach numbers. The Challenge Paul was working with a complex geometry composed of 112 distinct zones. The […]
Chris Nelson is the Chief Scientist for CFD at Innovative Technology Applications Company, LLC. Recently, one of his focuses has been on solving complex problems in jet noise simulation. The Challenge Chris runs his CFD cases on the ITAC computer in Missouri and a host of other remote high performance computing (HPC) systems. The jet noise simulations were mostly run on DOD HPC systems. He generally works from home, so […]
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 […]
Chasing the sun 3000km across the Australian Outback is a grueling test. And doing it in a solar-powered vehicle is an even bigger challenge. But every two years teams from around the world converge on Darwin, Australia, to make the journey to Adelaide in the solar-powered cars they have engineered specifically for the Bridgestone World Solar Challenge. The Stanford Solar Car Project, a student-run, nonprofit organization within Stanford University, has […]
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 […]
Researchers at U.S. Naval Academy and George Mason University use Tecplot 360 to clearly visualize horseshoe vortices in flow over wall mounted cube for first time. If you’ve ever stood on a beach and felt the sandy surface collapse beneath your feet as the waves washed over them, you’ve experienced firsthand the powerful effects of fluid flow. When the waves meet the surface boundaries commonly called your toes and feet, they […]
Case Study: Tecplot Chorus integrates with KARALIT CFD to save time with mesh-free CFD simulations and analyses The Immersed Boundary (IB) methodology, a mesh-free technique for running CFD simulations, has been around since the 1970s. Instead of running Navier-Stokes equations on grids that conform to the shape of an object, as is done with meshing, the IB technique immerses a CAD model of the object into a Cartesian grid and […]
Tecplot 360 helps Stanford University students optimize design of solar-powered car to compete in the Australian Outback’s World Solar Challenge The sun shines down upon the immense Australian Outback like nowhere else, drenching the land in solar energy that begs to be tapped. Where better to stage the World Solar Challenge, a design competition established to find the world’s most efficient solar-electric car? Every two years, some of the brightest […]
