Vous découvrirez au cours de cet atelier comment les outils CD-adapco permettent aux acteurs du secteur automobile d’améliorer les performances de leurs systèmes et de trouver la meilleure solution au regard du cahier des charges et du temps imparti. Notre invité Valeo vous présentera son expérience sur l’utilisation de notre solution STAR-CCM+ pour le développement de ses systèmes thermiques.
Still water resistance has been the traditional way of optimizing ship hulls since the time of William Froude. In the last few years, hydrodynamic optimization of hulls has been carried out with consideration to their operating profiles as opposed to design condition alone. However, ships sail in waves most of the time, so how can the resistance of the hull in waves be improved? The answer is positive: the potential, especially in short waves, is far from being negligible. On the other hand, optimization for minimization of added resistance in waves is far from trivial, due to the difficulty...
Modeling Complex Motions and Simulating Reality with Overset Mesh
Modeling of fluid flow around moving objects is relatively commonplace, so long as the motion involves a single body moving in an easily prescribed manner. However, as engineers increasingly demand greater simulation realism an effective approach to modeling multiple interacting bodies with arbitrary motion is required. This presents a major challenge for CFD engineers restricted to software that used more traditional and computationally expensive dynamic mesh approaches. Overset Mesh technology avoids the limitations of dynamic mesh, enabling the study of real-world moving body simulation...
Time Changes All Things…Even Air Flow & Temperature
"The only constant is change." This quote is attributed to the ancient Greek philosopher Heraclitus, and it is as true of engineering simulation as it is of life. Every situation we wish to simulate is in reality a time-varying situation, whether on the macro-time scale of days or weeks, or on the micro-time scales of milliseconds at which turbulence operates. Yet the vast majority of engineering simulations, including thermal simulations of electronics, are performed as steady situations. Why can we do this? When is steady-state a legitimate assumption? This webcast examines the meaning of...

CD-adapco is pleased to announce our inaugural North American Vehicle CFD Conference taking place in Livonia, MI on June 2nd. This complimentary event will be a great opportunity to meet with colleagues in the ground transportation industry to discuss how CFD simulation helps engineers Discover Better Designs, Faster.
A key feature in the latest release of DARS, v3.02, is a new laminar flame speed library generator for the ECFM combustion models in STAR-CD/es-ice. This feature improves the accuracy of in-cylinder combustion simulations, allowing for better design of combustion systems to provide more performance with lower fuel consumption and lower emissions.
CD-adapco is pleased to announce the 3rd biennial Oil, Gas and Chemical Conference taking place in Houston, Texas on May 19th and 20th. Leading professionals will share their experiences in the application of CFD in the oil & gas and chemical industries to improve designs and reduce cost, without compromising safety.
