Application: Design of Electronics Cooling with CFD
Posted Thu October 25, 2001 @06:24PM
Print version Email story Tweet story
Application High powered electronic equipment generates a considerable amount of heat - often in very confined enclosures. Furthermore, electronic equipment has narrow thermal operating conditions. This is why thermal control has always played an important role in the design of electronics which must be extremely reliable, such as on board aircraft.

Complicating the design of airborne electronics is the fact that the environment is harsh with ambient air temperatures ranging from -55 to 100 C or more, and weight and volume constraints demand a compact design.

Natural convection alone is not sufficient to keep airborne electronics at reasonable temperature levels, therefore, designers have turned to forced convection. On board advanced aircraft, such as fighters, an environment control system is used to supply cool air to the electronic equipment. This type of cooling creates problems due to pollutants (dust, sand, metals, liquid droplets) in the flow which can cause micro electronic shorts and/or abraid the electronic surface.

To solve the problem, engineers have turned to passing the cooling flow over fins. The only accurate way of predicting pressure drops and temperatures is to perform a CFD analysis. The simulation yields cooling performance and pressure drops for aid in fan selection. The CFD results can also be used as input to a detailed thermal analysis of the circuit board.

Through the use of CFD, advanced designs of airborne electronics are made possible.

News AEA Technology has announced the release of CFX-5.5, the latest addition to their CFD product line.

CFX-5.5 offers a number of improvements over previous versions including:

  • Improved meshing with proximity detection and general interface support
  • Improved multiphase modeling
  • Free surface modeling
  • Single and multiple step chemical reaction models
  • Multiple frame of reference modeling
  • Advanced turbulence modeling including a Shear Stress Transport (SST) model
  • A new post-processor featuring a scripting language
CFX-5.5 combines the world-class meshing and solver technology of earlier CFX-5 releases with new physical modeling, meshing and post-processing tools that make it possible to apply the most powerful and precise CFD technology to a very broad range of problems. -- Chris Reid, President and Chief Executive Officer of CFX

Application: CFD for Ship and Yacht Design
Posted Fri October 19, 2001 @04:48PM
Print version Email story Tweet story
Application Ship and yacht designers are increasingly turning to CFD to help in the design of hulls and propellers. Recent advances in fluid modeling allow designers to tackle tough problems such as wake prediction, propeller-hull interaction, and acoustics. Military applications include reducing acoustic and non-acoustic signatures (such as the wake field observed by synthetic aperture radar).
The naval and commercial ship design communities have long needed a predictive capability to address the complex interaction between a ship's boundary layer, the nonlinear free-surface, and the propulsor. In commercial ship design, the prediction of near-field flows is central to the problems of unsteady propeller loads, cavitation, and propeller-induced hull vibrations. The solution to these problems requires detailed knowledge of the turbulent stern flow (including thick and perhaps separated boundary layers), bilge vorticity, and propeller/hull interaction.

Another interesting application is the prediction of ship hydrodynamic response, how the ship pitches and rolls, in heavy seas.

There are several CFD codes available which are tailored for hydraulic analysis.

The use of CFD in the ship building industry has been spured by the expense and time-consuming nature of hydrodynamic tank testing.

Team NZ Using SGI for Boat Design
Posted Thu October 18, 2001 @05:21PM

Hardware SGI has supplied defending America's Cup champion Team New Zealand with UNIX workstations to be used for CFD analysis of the boat's hull, keel, wings and sails.
Although many boat parts are now totally computer designed, for some key parts, such as the hull, there is still no substitute for the traditional method of physically building models and testing them in tow tanks.
