AVL Offers Integrated Approach to Exhaust Simulation
Posted Mon October 21, 2002 @01:46PM
Print version Email story Tweet story
News The introduction of more stringent European and world-wide standards for engine emissions steadily increases the effort to develop new exhaust after-treatment systems. In order to reduce costs and time, the application of reliable computer models has become an indispensable part of any development in emission control and powertrain management. In early stages 1D simulation tools help perform basic system analysis and define first designs of catalytic converters and soot particle filters. 3D simulations are applied to evaluate the overall performance of fully integrated after-treatment systems and to tune final designs. In order to meet these requirements, AVL has recently introduced 1D approaches that are integrated within the thermodynamic and engine cycle simulation code BOOST, and 3D models as part of the CFD code FIRE.

Print version Email story Tweet story
News The latest version of CFX-TASCflow, the leading computational fluid dynamics (CFD) software for mechanical engineering, offers a new improved cavitation model, solves problems four times as large as the previous release, provides significant usability improvements and support of new 64-bit systems including Itanium. The new cavitation model, which is based on the volume of fluids (VOF) approach, provides solutions for many common application areas such as hydraulic flows in pumps, turbines, inducers and fuel injection systems. The new release supports 64-bit architectures such as HP UX 11, Solaris 8, and AIX 5I, making it possible to access more memory and solve problems of eight to ten million nodes in size in serial mode; more in parallel mode. "CFX-TASCflow Version 2.12 further advances CFXs leading position in the turbomachinery industry and helps demonstrate why leading companies such as Siemens, Sulzer Innotec, Dresser-Rand and many others depend on our software as their primary design tool, said Dr. Michael Raw, Vice-President CFX Product Development. We are continuing to expand the capabilities in our CFX system of software, ensuring that our CFD tools and services are uniquely qualified for solving real-world industrial problems.

Application: CFD Aids Thrust Reverser Design
Posted Wed October 16, 2002 @01:21PM
Print version Email story Tweet story
Application It is by now standard practice at Boeing to design basic aerodynamic surfaces, such as the wings, engine nacelles, and fuselage, using computational fluid dynamics.

It is less common and often more difficult to use CFD to analyze more complex parts of the airplane, such as high lift systems, engine compartments, auxiliary power units, or the behavior of the efflux from engine thrust reversers.

When dealing with thrust reversers, designers must know exactly where the exhaust plumes go, and they must know it early in the design cycle, because it affects such basic decisions as the placement of the engine on the wing. The enabling technology and research group at Boeing's commercial aircraft unit has developed a computer simulation that provides an early look at thrust reverser exhaust plumes.
