Print version Email story Tweet story
ESI Group CFDRC is offering two application specific modeling courses.

Fuel Cell Multiphysics Course
February 12-13, 2002
Huntsville, AL
This course will discuss the Theory and Solution Strategies for current state-of-the-art modeling and simulation techniques for Fuel Cells and Fuel Reformers. Utilizing relevant examples from the industry, the instructors will demonstrate the value of simulations and discuss the assumptions made, along with their inherent limitations.

Biomedical Seminar
February 6, 2002
Anaheim, CA
This seminar will feature demonstrations of how the CFD-ACE+ software can be applied to biomedical device modeling. Sample cases of hybridization, microdispenser, lab-on-a-chip and system level simulation, as well as parametric simulations of DNA filtration chips will be shown.

Application: CFD Reduces Design Time from 1 Year to 4 Weeks
Posted Fri January 11, 2002 @02:22PM

Application By adding computational fluid dynamics (CFD) analysis to its product development process, Blender Products was able to design a new HVAC air mixer in four weeks, down from the one year required for its previous mixer. Designing that product had required many rounds of prototype testing, each taking several months, to determine how efficiently the device mixed two streams of air. For the new mixer, the company ran multiple CFD analyses to evaluate different design iterations in software. Each iteration took less than a week. The results guided designers as to what elements could be removed to reduce manufacturing costs while maintaining mixing efficiency. Nearly all prototype testing was eliminated, allowing Blender Products to quickly capitalize on a new market opportunity. The company also uses CFD analysis to evaluate how its mixers will work when added to existing installations. This formerly required testing of a scale model, a process that took two to three months. The company now accomplishes the evaluation without a scale model and is done in one week.

Application: CFD Fixes Faulty Mixer

Application Philadelphia Mixers used MixSim, a dedicated mixing analysis software package, to solve a problem with a pH adjustment system in a baffled mixing tank. The complete analysis, which required several simulations, took only one day, considerably less than the week or more that would have been required if general-purpose computational fluid dynamics (CFD) software and grid generation tools had been used. Most of this time would have been required to build the model because of the complex geometry of the system and the fact that it contained both stationary and moving parts. The mixing-specific software used set up the model automatically in response to parameters entered by the user. "After I entered a few specifications, the software created the geometry and the analysis mesh in less than 5 minutes," says Wojciech Wyczalkowski, director of technology at Philadelphia Mixers. After the first analysis showed the reason for the fluctuating pH, Wyczalkowski ran seven more analyses to improve the design. By the end of one day, he had an optimized solution that the customer has since implemented successfully.

Application: CFD Wins Races

Application CFD analysis has played an important role in the performance of winning motor racing teams this year. The dominant Ferrari Formula 1 Motor Racing Team claimed both the Drivers' and Constructors' World Championships. The Ferrari Technical Team utilized extensive CFD simulations with FLUENT to hone the aerodynamics package.

At the Indy 500 race last May, cars manufactured by Italy-based Dallara Engineering finished 1-2-3. Dallara recognized that CFD was essential to their aerodynamic design process and they chose FLUENT to be an integral part of it.

And in the competitive world of NASCAR racing, CFD has found a home in one of the best teams - Joe Gibbs Racing.

Team owner Joe Gibbs remarked, "To win at anything you have to surround yourself with the best. That is why we use FLUENT CFD software to visualize and analyze fluid flows such as air flowing over the vehicle or water flowing through the cylinder head. FLUENT is an integral part of keeping our race teams at their best."

Application: CFD Used to Study Surface to Air Missles
Posted Mon December 10, 2001 @02:23PM

Application Scientists at the NAS Division's Applications Branch have used NASA's Cart3D CFD software to analyze the unsteady flight of infrared-guided, man-portable surface-to-air missles (SAMs).

The Cart3D solver's capabilities were extended to simulate the unique flight characteristics of the SAMs which make them difficult to simulate computationally. Scientists used the NASA Advanced Supercomputing facility at Ames Research Center to conduct the steady and unsteady simulations on both a 1024-processor and 512-processor SGI Origin 3000 system. More than 720 simulations were completed on meshes totaling almost 2.4 billion cells.

"Results from preliminary NAS studies presented to the DIA have been met with enthusiastic support," said Mike Aftosmis. The steady and unsteady results have shed new light on the flight characteristics of these missiles.
The Cart3D package is an inviscid Cartesian grid flow solver which provides end-to-end simulation of three-dimensional flows around complex vehicles.
