Computational Fluid Dynamics (CFD) ist eine über Jahre erprobte Software-Simulation zur Detailentwicklung von Apparaten und ganzen Anlagen. Jetzt entdeckt auch die Pharmaindustrie die Vorteile dieses Verfahrens.
STAR-CCM+'s overset mesh technology was used to simulate and analyze the glass forming process. Here are shown the velocity contours along the center plane of the glass gob.
A numerical method of modeling oil jet piston cooling
To meet stringent emission regulations and high power requirements, peak cylinder pressures and specific power of petrol engines have increased dramatically in recent years, resulting in higher thermal loading of in-cylinder components such as pistons. To keep maximum temperatures securely below an acceptable limit, modern engine pistons are oil cooled. An oil jet, injected from a nozzle tube on the crankcase, impinges on the underside of the piston and achieves effective temperature control. On the one hand this cooling concept can ensure the required durability and reliability of pistons...
Gas-Liquid Stirred Vessel
Many chemical processes involve mass transfer between gas and liquid phases. A stirred tank is a common gas-liquid contactor. Gas is injected in to the tank via sparger or lance. Single or multiple impellers are used to increase the contact are between the gas phase and liquid phase. The shear introduced by the stirring action causes the bubbles to break-up increasing the contact surface or interfacial area. The interfacial are directly determines the mass transfer across the phases and thus the reaction rates. STAR-CCM+ can model the complex vessel geometry using polyhedral or trimmed mesh...
Migration from STAR-CD to STAR-CCM+ at the BMW Group
This presentation will show the results of the overall migration from STAR-CD to STAR-CCM+ at the BMW Group during the years 2010-2011. After exploring the challenges present the BMW product development procss, the presentation will give an overview of the usage of computational fluid dynamics by the different departments at BMW. After that, the presentation will focus on the migration project. This will include the project objectives, the project timeline, the project structure as well as the collaboration between CD-adapco and BMW during the project. The last part of the presentation will...
Isosurface of Q-criterion colored by vorticity showing rotor wake from a ROBIN body. This simulation was generated using an overset mesh.
ART Grand Prix has been engaged in the Formula 3 Euroseries Championship since 2003. The regulations allow teams to work intensively on external aerodynamics to improve the performance of their Formula 3 car. Therefore, many wind tunnel tests were performed to obtain experimental data which permitted to characterize the global aerodynamic performances of the ART F3 car and to lead to many developments. To bring more efficiency into the development process of external aerodynamic parts, the use of CFD, as a tool in the evaluation and understanding of aerodynamic performances, became more and...
