Application: CAD-Integrated CFD Software Helps Design Innovative Flush Valve in Less Time
Posted Thu August 17, 2006 @10:10AM
Print version Email story Tweet story
Application EFD.Lab CAD-integrated computational fluid dynamics (CFD) software saved time in the design of an innovative flush valve by enabling Johnson Design engineers to solve design problems utilizing software rather than hardware prototypes.

A unique feature in Johnson Designís Denali Flushometer flush valve is that it delivers a fixed volume of water independent of the position of the restriction on the rolling diaphragm which is randomly installed at various positions during the valve assembly. Johnson Design Engineering Manager Dustin Borg used EFD.Lab to evaluate the performance of the valve as the restriction was rotated 360 degrees in order to ensure that it delivered the right amount of water in each position.

News SoftPredict, a subdivision of Rotexo GmbH & Co. KG, have released their all new combustion software COSILAB2.

The software handles arbitrarily complex gas-phase chemistry in flow simulations including combustion, exhaust gas after-treatment, and pollutant formation. It benefits from an easy-to-use graphical user-interface that handles preprocessing of thermodynamic and molecular databases, and of reaction mechanisms -- all in the most popular and internationally accepted data formats.

Application Unlike general-purpose CFD companies, Flomerics has always been focused solely on a single industry: electronics. The idea behind development of Flotherm was to build in electronics intelligence on top of CFD. This intelligence would, in turn, be used to make problem setup, modeling, and analysis much faster, more efficient, and more accurate for engineers who design electronics.

In Taking the Heat Out of Electronics, Desktop Engineering speaks with Sherman Ikemoto, Business Development Manager for Flomerics Inc., and Flomerics users on what Flotherm brings to electronics design.

Application Steve Karman and Robert Wilson,
UT SimCenter at Chattanooga,
University of Tennessee at Chattanooga

Modeling of free surface flows for hydrodynamic applications can be accomplished using surface fitting methods for low to medium Froude numbers. But when the Froude number is larger, such as flows associated with steep and overturning waves, the fitting methods encounter difficulties.

The University of Tennessee SimCenter at Chattanooga has implemented a multiphase surface capturing approach to handle these higher Froude number cases, Fr > 0.4. This approach has been applied to several validation cases, including the R/V Athena research vessel shown in this article.
