Dr. Ross Haywood with Hatch Ltd., Australia has been an early user of the new release. "I found the new release to be absolutely first-rate," Haywood said. "The ability to use all of the models together makes it possible to apply CFX-5 to a much wider range of applications. That's significant, because CFX-5 has long been unique in its ability to solve larger and more complex problems than the other codes that I am familiar with. I am extremely pleased at the rate at which this code has been improving."

Major enhancements have been added to multiphase and free surface capabilities. The number of phases in a multiphase analysis is now unlimited, so that fluidized beds and particle separators with multiple particle sizes can be simulated with ease. The free surface flow model has been expanded to include a bulk energy equation, low speed variable density, fluid-specific additional variables and fluid-specific multicomponent fluids. These capabilities extend the applicability of free surface models to include, for example, mold filling and contaminant dispersion. A surface tension model is now available which allows the engineer to predict flows accurately in capillary tubes and the coalescence of liquid droplets.

Numerical models in The Dalles tailrace are being used to support efforts to reduce fish mortality associated with fish passaging of the hydroelectric project. At The Dalles, several locations have been proposed for a high flow outfall that would move fish around the dam rather than through the turbines or over the spillway.

One of the oldest and finest establishments of its kind in India, the Indian Institute of Science (IISc) has grown into a premier center of research and advanced instruction. Its Combustion Gasification and Propulsion Laboratory works mostly on fundamental research in combustion and its applications in industry.

A recent research project focused on investigating the effects of flow recirculation on the efficiency of a gas furnace, the goal being to optimize the position of the fuel nozzles. CFD simulations were conducted in parallel with experimental work on a typical preheated-air furnace.

The user interface has also been significantly enhanced to further improve useability.

Add the rapid performance-screening "Plus" module, CFX-BladeGenPlus, and harness the power to readily obtain 3D viscous solutions with a level of effort equivalent to streamline curvature approaches.

CFD has become an important design tool in nearly every industrial field because it provides values for fluid velocity, fluid temperature, fluid pressure and species concentrations throughout a flow domain. But CFD analysis to date has been limited by post-processors that provide results relative to a fixed user position that discourage discovery. Virtual Vantage software harnesses the power of virtual reality to convert the flow domain into a computer-generated world that the user can immerse himself or herself within in order to bring their fullest potential of human thought and skill to bear on the problem.

Engine cooling simulation has been done for several years with 1D tools being used to determine pressure losses and flow rates in cooling circuits. The more complex flow patterns in cylinder head and jacket are simulated with full 3D CFD to determine convective heat transfer coefficients.

BMW simulates the vehicle's coolant flow with FLOWMASTER2, which enables a one-dimensional description of the whole system. Flow in the engine coolant jacket, which is much less predictable, is described three-dimensionally by the CFD programme STAR-CD, from CD-adapco.
