It is less common and often more difficult to use CFD to analyze more complex parts of the airplane, such as high lift systems, engine compartments, auxiliary power units, or the behavior of the efflux from engine thrust reversers.

When dealing with thrust reversers, designers must know exactly where the exhaust plumes go, and they must know it early in the design cycle, because it affects such basic decisions as the placement of the engine on the wing. The enabling technology and research group at Boeing's commercial aircraft unit has developed a computer simulation that provides an early look at thrust reverser exhaust plumes.

[ed] - Depending on your requirements, I think you will find the major CFD vendors to be very amicable towards students. You should try to contact the CFD vendor directly and explain your situation. Good luck and please let us know what happens.

During its development a major focus was put particularly on user-friendliness, enabling the design engineer to carry out complex calculation tasks with a few operations. The basis for this is the integrated CFD Workflow Manager which guides the user through the CFD workflow, hence considerably reducing training and project turnaround times. Although also available on UNIX platforms, the look and feel of the graphical user interface resembles the quasi standard set up by Microsoft’s Office applications, making it extremely easy to use.

The combination of FIRE with the BOOST one-dimensional gas-dynamic simulation tool and HYDSIM for the one-dimensional calculation of injection system components represents a software package capable of providing a comprehensive solution for engine thermodynamics, flow, mixture formation, combustion and aftertreatment system related analysis and optimisation tasks.

es-tools workshop: es-aero for external aerodynamics and es-uhood for underhood flow and thermal simulation

5th November 2002, Nuremberg, Germany
6th November 2002, Paris, France
7th November 2002, London, UK
8th November 2002, Milan, Italy (es-aero only)

This workshop is aimed at providing both experienced CFD engineers and newcomers alike with a better understanding of how CFD simulations in combination with our knowledge based expert systems, es-aero and es-uhood, is playing an ever increasing role in the design and development of vehicle external aerodynamics and vehicle underhood flow and thermal management.

During the workshop you will see how using our products es-aero and es-uhood, can help you reduce development costs and shorten your vehicle simulation time. es-aero provides a knowledge-based solution for a no compromise fast and accurate simulation of flow around complex 3-D vehicles, while es-uhood facilitates rapid simulation of flow and thermal processes inside the complex engine compartment. Both products are designed to conveniently handle the following activities: Preparation and cleaning of CAD surfaces and geometry - generation of appropriate CFD grids - an effective choice of boundary conditions and physical models - control of the CFD solution - post processing of results.

You will also have an opportunity to hear the experience of SAAB using these tools and discuss your concerns and requirements with some of our most experienced engineers.
