Events: Flow Induced Noise Simulation Seminar
Posted Wed May 24, 2006 @04:05PM
Print version Email story Tweet story
Announcements LMS International will host a webseminar on the simulation of flow induced noise on June 1st, 2006.

The aero-acoustics simulation tools from LMS help you evaluate the noise from unsteady flow phenomena like vortex shedding and turbulent boundary layers by coupling Computational Fluid Dynamics (CFD) methods with Computational Acoustics.

The aero-acoustics simulation tools from LMS offer a set of capabilities and user-friendly interfaces to transform the time-domain CFD data into equivalent aero-acoustics sources in the frequency domain. State-of-the-art acoustic BEM analyses will then return accurate predictions of the noise levels generated by these sources.

Announcements Advanced Design Technology (ADT) will host a two day aero/hydrodynamic design training workshop for incompressible flow turbomachinery applications on June 29-30, 2006 in Detroit.

The workshop will introduce the inverse design process and compare this with conventional design. It will enable participants to apply the unique features of TURBOdesign-1 3-D inverse design code, coupled with TURBOcfd in the hydrodynamics/aerodynamics design of their own specific blade row, under the supervision of experienced design staff from ADT.

News Flomerics' Flovent software for airflow prediction in buildings has been awarded the Expertís Choice Award for Software from Controlled Environments Magazine. Flovent software was selected by an independent panel of judges as the best software package in the contamination protection and controlled environment industry.

The award stated that: "No matter how complex the airflow application is, this modeling software enables the user to understand it more comprehensively through the medium of virtual reality and computer 3-D animation." Dr. Andy Manning, Director of Engineering for Flomerics, Inc. said that: "We are extremely pleased that Controlled Environments Magazine has recognized the industry-leading capabilities of Flovent software through their Expert's Choice Award."

Coupled CFD and FEA Analysis Opens New Design Avenues
Posted Tue May 23, 2006 @12:19PM

News The coupling of structural and fluid analysis allows designers to examine the effects of fluid-structure interaction, effects which can be used to improve the overall design, such as a Formula One car's wing which deflects at certain speeds to achieve different performance.

An Engineer Online article explores the technology behind coupling FEA and CFD analysis and the benefits of doing so.

In the 'real world', physical phenomena tend to act together: an aerodynamic wing, for instance, needs to be modelled for stress, vibration and fluid flow. The design of these kinds of systems using single-phenomenon behaviour currently entails many back-and-forth iterations until an optimum is reached.

No Mesh, No Fuss

News A Mechanical Engineering Magazine article describes the use of meshless finite element analysis. Rather than basing the computational method on a discrete mesh, the algorithm works with the analytical CAD surfaces defining the model.

"Right now, CAD systems have one framework for geometry and materials distribution, and analysis systems have another for behavior," Subbarayan said. "We've provided a mathematical framework that unifies geometry, material distribution, and behavior."

In the future, Subbarayan and his fellow researchers would like their software to be able to analyze for the coupled physical phenomena that are often a part of real-life engineering problems.
