"We created a single model, added boundary conditions to determine hydrodynamic forces, and distributed them across the blades," says Gerald Lynch, Sigma Design president.

With 16 drivers competing in NASCAR's Nextel circuit – including Ryan Newman, who notched eight wins and 11 pole positions last year – it is easy to forget that only three years ago DaimlerChrysler's Dodge division was returning after a 25-year absence from stock car racing's most prestigious tour.

To gain a perspective on just how far Dodge has come, go back to 1999: DaimlerChrysler had fewer than 500 days to design and build a competitive car for the 43rd Daytona 500 in February 2001. The aerodynamics team accelerated its work with computational fluid dynamics (CFD), advanced visualization, and scale-model wind-tunnel development to augment traditional full-scale wind-tunnel and on-track testing. This combination of processes has since become the standard for DaimlerChrysler race programs and commercial cars.

Taking place on Stand 26 in the IT & software zone the demonstrations will focus on the need to simulate the thermal interactions between the under hood fluid systems found in the vehicle. Such systems include: engine cooling, lubrication, under hood airflow and air conditioning.

“Of particular importance is the packaging of the cooling pack. With Space in the engine bay at a premium, heat exchangers such as the radiator, oil cooler and air conditioning condenser often overlap each other. As a consequence the component with the most overlapping, experiences airflow at a higher temperature than desired, which can impair the performance of the system it resides in” – explains Paul Burns, Automotive Product Manager, Flowmaster Group.

Companies around the world -- in a wide range of industries including aerospace, chemical processing, power generation, automotive, oil and gas, heating, ventilation and air conditioning, and many others -- depend upon CFX software. The latest release of CFX-5 continues the rapid advancement in CFD core technology development and leverages the ANSYS technology to increase integration into the engineering design cycle.

Ingress of warm moist air during cold-store door opening is a major issue in refrigeration plants, as it increases energy consumption and can also cause an undesirable rise in product temperature. Moisture infiltration itself can produce food safety problems in chill stores and can jeopardize personnel safety in frozen stores as the moisture turns to ice.

The British Department for Environment, Food and Rural Affairs (DEFRA) has commissioned the University of Bristol (FRPERC) to look at this problem in partnership with Anglo Dutch Meats (UK) Ltd; ACS&T Wolverhampton Ltd., Thermoscreens Ltd., Northern Foods Plc and Ballymoney Foods Ltd. The aim of the project, which is part of the LINK programme, is to reduce infiltration through doorways and thereby reduce the effects on temperature control, safety and energy consumption.
