Concepts NREC Turbomachinery Experts Available at Turbo Expo 2012 and Engine Expo 2012
Concepts NREC (CN) today announced that its turbomachinery experts will present two technical papers at ASME Turbo Expo, at the Bella Center in Copenhagen, Denmark, June 11-15, 2012. The papers will highlight the use of modern design software to develop asymmetric twin-entry turbines and ported shroud compressor housings, both used in turbocharging. CN will also present an overview of its design software, Agile Engineering Design System(R), on the exhibitor stage, and will be exhibiting in Booth #2109. Concurrently, CN will be exhibiting at Engine Expo 2012 in Messe Stuttgart, Germany, June 12-14, 2012, Hall 3 Stand 3249.
Technical Paper Presentations at Turbo Expo On June 12 at 11:45 a.m., during the session "Turbochargers: Design and Optimization," Dr. Nicholas Baines, Distinguished Corporate Fellow, will present the paper "Meanline Modeling of Radial Inflow Turbine with Twin-entry Scroll." Twin-entry turbines are widely used in turbocharging as a means of using the exhaust pulse energy of multi-cylinder engines. For modern engines where high levels of exhaust gas recirculation (EGR) are required, an asymmetric twin-entry turbine has been shown to have considerable advantages; however, such turbines require a more developed approach to analysis and design than usual. Dr. Baines will describe the meanline model for a radial inflow turbine with a twin-entry scroll that has been developed to address this.
On June 14 at 3:00 p.m., during the session "Centrifugal Compressors IV (Design and Optimization)," Dr. Shuo Li, Senior Engineer, Software Trainer, and Project Manager, will present the paper "Meanline Modeling of Ported Shroud Turbocharger Compressor." The requirements for higher fuel economy and better diesel and gasoline engines demand a wider range in turbocharger compressor operation. Ported shroud compressor housing is one of the most commonly used techniques for compressor map width enhancement. Although the general mechanism of such a flow feature is well understood, there are no readily available design tools to guide the engineers at the preliminary design stage. Designers have had to rely on three-dimensional (3D) CFD tools to sort out many design variables, but these tools can be prohibitively expensive. In this presentation, Dr. Li will explain how to develop a ported shroud compressor model on top of a commercial meanline compressor design program to obviate the need to use expensive 3D CFD tools.
CN Design Software Presentations at Turbo Expo On June 12 at 2:30 p.m., CN's Senior Vice President of Software and Chief Engineer, Dr. Colin Osborne, will deliver the presentation "Clean Sheet Turbocharger Designs Using Expanded Agile Turbomachinery Systems from Concepts NREC" on the Exhibitor Presentation Stage.
In Booth #2109, CN's Drs. Osborne, Baines, and Li, as well as Dr. Louis Larosiliere, Director of Aero/Hydro Design, and Fred Becker, Director of Engineering Sales, will be on hand to discuss any turbomachinery challenges that attendees may have, and to demonstrate the Agile Engineering Design System, the only commercially available design and analysis software that encompasses and integrates the entire engineering process for radial, axial, and mixed-flow turbomachinery components.

CN at Engine Expo Optimizing turbocharger design and development has become increasingly important as governments around the world demand compliance with increasingly stringent emission and noise regulations. CN's Turbomachinery Specialist Carl Fredriksson, and Managing Director of EMEA Illias Mustafa will be on hand in Hall 3 Stand 3249 to discuss how the unique combination of CN's turbomachinery design expertise and comprehensive CAE/CAM software helps organizations with the design and development of turbochargers, an integral element of engine development today.
