Application: Research Could Lead to Less Airport Noise
Posted Thu September 23, 2004 @04:52PM
Print version Email story Tweet story
Application From a Madison County Record article:

Airplanes fly over Kader Frendi's home in Madison frequently, and the roaring of the craft's approach to the airport serves as a reminder of research he is conducting at The University of Alabama in Huntsville.

Frendi is searching for ways to reduce noise associated with the takeoff and landing of aircraft. He has been investigating the science of noise generation and noise reduction during most of his academic career. He joined UAH's mechanical and aerospace engineering department five years ago. Computational fluid dynamics (CFD) uses computers to solve complex equations that model a problem of external or internal airflow over vehicle shapes.

"One of the big concerns in the aeronautical field is the noise level generated by the takeoff and landing approaches of airplanes," Frendi said. "Most people don't know it, but during takeoff and landing the noise from the airframe is almost equal to the noise made by the airplane's propulsion system." Most of the noise during the plane's approach to the runway is generated by the landing gear, the wing and the moving parts of the wing.

ANSYS FLUENT Fluent, Inc., the world's leader in computational fluid dynamics (CFD) software and services has been awarded a contract by the U.S. General Services Administration (GSA) to sell products and services to Federal customers through the GSA program, Fluent announced today.

“We are very excited about the opportunity to better serve our current and future Federal customers as a part of the GSA,” said Swaminathan Subbiah, Vice President - US Operations. “This will make procuring Fluent’s software much more streamlined and cost effective for government agencies.”

This contract enhances Fluent’s ability to provide its products to Federal customers, enabling them to purchase the products and services they need quickly and effectively using pre-established rates. GSA was created by Congress to improve government efficiency and help federal agencies better serve the public. GSA, comprised of 13,000 associates, provides services and solutions for the office operations of over one million federal workers located in more than 8,000 government-owned and leased buildings in 2,000 U.S. communities.

Federal customers can access information about Fluent products and services through the GSA Schedules e-Library by searching by the contract number (GS-35F-0810P), or company name “Fluent”.

Fine Tuning Aerodynamics

News Linux Networx has posted an article [pdf] on the use of CFD and cluster computing at Orbital Sciences.

Like many aerospace companies and organizations, Orbital Sciences depends on CFD; specifically, the company is using it to predict how rockets and satellites will perform in various environments. CFD works by turning the region of flow into discrete cubic-like cells. The governing fluid equations are then used to set up a large matrix, which can then be solved using a high-performance computer system.

In the past, Orbital had been limited by a computer system that would get bogged down, resulting in a significant slowdown for CFD problems that could involve more than one million cells.

“In the case where a larger problem was deemed mission critical, there invariably was a need to justify the cost of outsourcing smaller problems that had to be completed, including projected payback on the outsourced engineering work,” said Richard Straka, Vice President and Chief Engineer of Orbital’s Launch Systems Group. “Ultimately these justification efforts pulled engineering talent from its core competencies to convince management to spend the money necessary to support the outsourced CFD.”

News Linux Networx has announced a new professional service that provides detailed simulations of the airflow in current and proposed data centers. By partnering with Fluent Inc, the market leaders in computational fluid dynamics (CFD), Linux Networx can provide detailed CFD animations of datacenter airflow by running Fluent's Airpak modeling software on a Linux Networx Evolocity® cluster. Airpak simulations reveal the airflow and temperature distribution in a datacenter to better understand potential ventilation problems before a computing system is installed.

"Understanding datacenter airflow is extremely valuable because improper ventilation can cause systems to overheat and compromise productivity," said Padmanabhan Iyer, director of training and professional services for Linux Networx. "By partnering with Fluent to provide Airpak modeling, Linux Networx can help organizations ensure proper airflow in their datacenters to maximize their cluster's return on investment."

Events: Axial Turbine Design and Optimization Course
Posted Mon September 20, 2004 @04:02PM
Print version Email story Tweet story
Announcements SoftInWay, Inc., developer of software products for turbine design, including AxSTREAM, a powerful software suite that encompasses the complete engineering process of a gas/steam axial turbine flow path, is pleased to announce a new education course: Axial Turbine Design and Optimization. The session will be held November 9-11 in Burlington, MA.

For registration and details, please see the course website

This practice and design oriented course is based on over 400 years of experience in turbomachinery design and engineering by SoftInWay's team. It addresses all engineering disciplines involved in axial turbine design and modernization by providing theoretical background, design practice, and operational characteristics for all types of axial turbines; compressed in an intensive 3-day session.

Spanning a concepts-to-details process of axial turbine design/retrofitting, the course will enrich engineers with application-oriented guidelines for new/existing turbine flow path designs along with design techniques for the entire flow path and its optimization, including turbine flow path CFD analysis.

Early bird registration is welcomed with a 10% discount (deadline 9/24/04). Other discounts are available.
