Fluent Help Needed

Help Desk baixn writes "The idea is to examine the thermal field surrounding a combusting sphere of solid propellant. Given the heat release rate determine the thermal field surrounding this sphere. The spherical mass is 10 mm diameter and weighs 30 grams. The heat release rate is: Q=0Kcal/gm @ t=0ms and Q=2.1Kcal/gm @ t=20ms and Q=0Kcal/gm @ t=40ms.

My question is: Should I use heat transfer model or combusting model to simulate this case? How to simulate?

Any advice is highly appreciated.

Best Regards,
baixn"

ANSYS CFX ANSYS is providing its CFX software to the da Vinci Project, a Canadian entrant in the $10 million X PRIZE competition. The X PRIZE is designed to jumpstart the space tourism industry through competition among the most talented entrepreneurs and rocket experts in the world.

The da Vinci Project recently implemented CFX, computational fluid dynamics (CFD) software, to aid in the development of processes involving fluid flow, heat transfer and chemical reaction. Also added from the ANSYS software suite was ANSYS ICEM CFD, a post-processing tool to help streamline product development.

Application by Ricardo Barbosa Damian,
CIBER Equipamentos Rodoviários Ltda. (member of the Wirtgen Group)
and Marcus Reis,
ESSS

Modern, efficient and innovative, CIBER is located in Porto Alegre, Brazil and has as its core business the manufacture and sale of machinery and equipment for road construction and maintenance.

Experimental development of portable asphalt plant components requires time and is an expensive process. In order to offer products with lower energy consumption and more compact dimensions, and that meet environmental regulations, CIBER chose CFX-5 computational fluid dynamics software to assist in analyzing many of the complex processes involved in asphalt production. These processes include combustion, solids drying, liquid and solid mixture, solid-air separation and filtration and pneumatic transport of particles.

CD-adapco As the world’s two leading CFD (Computational Fluid Dynamics) companies, the CD adapco Group and Fluent Inc, compete for technical supremacy, the release of any new version of their CFD codes is a major event for the CAE industry. The latest version of STAR-CD was launched at the CD adapco Group’s European User Group Meeting in London, March 15-16, and clearly offers CFD users many new features and associated benefits.

Firstly, a choice of CAD-integrated options is now included ‘by default’. The STAR-Design option, for users without a CAD system, offers a robust built-in Parasolid solid-modeling kernel and fast meshing tools, and unlike most commercial CAD systems, it is available on all platforms including Unix, Linux and Windows.

Help Desk Glen writes "Any one with info on the latest combustion modeling techniques and would like to share it with me? I'm rather new to CFD and am having trouble tracking down freely available overviews etc. My Professor is very involved in the code side of life so I guess that what he wants to hear about, that and anything on grid generation would be warmly recived, thanks hope you can help.

CFdesign Blue Ridge Numerics, Inc. (BRNI) has announced that Richard Childress Racing (RCR) in Welcome, North Carolina, has selected CFdesign® for virtual prototyping fluid flow and heat transfer performance of automotive components and systems built in Pro/ENGINEER Wildfire.

Recognized as a one of the heavyweights of NASCAR, RCR has a reputation for finding engineering innovations that help current drivers Kevin Harvick, Johnny Sauter, Robby Gordon, Ron Hornaday, and Clint Bowyer cross the finish line first in Nextel Cup and Busch Series races across the country.

"CFdesign is perfect for our high-performance engineering teams," stated David Holden, a team engineer at RCR. "We build prototypes in Pro/ENGINEER Wildfire, hit a button, and instantly we're ready for a CFD simulation that delivers fast results on a workstation PC. If we want to investigate alternative designs, we make the changes in Wildfire and within minutes we're getting real-time results on the new designs from the Runtime Monitor in CFdesign."
