Yoshihiko Sunayama, Ph.D - Group Leader, CAE Group, Digital Engineering Dept. Suzuki Motor Corporation In the development of a sports motorcycle, a balance must be achieved between low drag to improve per formance and good air flow through the cooling system to maintain reasonable fuel economy. Typically, however, a low drag coef ficient (CD) and increased flow through the heat exchangers are contradictory in nature, as an improvement in one leads to deterioration in the other. With this in mind, Suzuki looked to STAR-CCM+ to help optimize their bike designs by studying aerodynamics and heat...
CD-adapco is pleased to announce that its industry leading simulation tool, STAR-CCM+, now includes a direct link to Abaqus FEA from SIMULIA, delivering fully coupled, two-way, fluid-str ucture interaction (FSI). Dynamics 31 - Read more
Wilson Sporting Goods Co. Teams with CD-adapco Wilson is taking its soccer balls to the next level in aerodynamics research using CD-adapco’s STAR-CCM+ software on Windows HPC Ser ver 2008. Dynamics 31 - Read more...
Drew Robb, freelance writer. In the quest to improve efficiency and per formance of gas turbine engines, manufacturers over the past few decades have steadily altered their designs to increase turbine inlet air temperatures. Although this achieves the desired result, it produces the side ef fect of over heating the blades - and that leads to low cycle fatigue failures. But with oil prices fluctuating and the industr y accepting the reality of the need to reduce carbon emissions, the tendency toward higher turbine inlet temperature continues unabated. This poses considerable challenges for the...
Anne Boorsma, Patrick Fitzsimmons, Dejan Radosavljevic and Stewart Whitworth, Lloyd’s Register ODS Technical Investigations and Analysis Consultancy, UK. Lloyd’s Register ODS has recently been involved with the investigation of a number of vibration and noise related habitability problems aboard feeder containerships of 2000-3000 TEU capacity having all-aft deckhouses; feeder containerships are relatively small vessels that transport car goes to and from large, long-haul container terminals.

Marco Giachi, Eng., Centro Studi Storici di Assomotoracing. Dr. Anthony Massobrio, CD-adapco. One of the most interesting aspects of competition motor racing is watching the gradual development of the vehicles’ technical features over the years, the most impor tant of which provide a snapshot view of leading aerodynamic design thinking of that time. It is impor tant to know the histor y of motor racing technology not only for purely cultural reasons, but for educational reasons too, in order to train young engineers and future aerodynamics designers.

Dr. Ignazio Maria Viola - School of Marine Science and Technology, Newcastle University, and Dr. Raffaele Ponzini - CILEA The America’s Cup is the oldest trophy in the world and the competing platform for the most advanced technologies in the marine field. In recent years, CFD has become the most powerful tool for both aero and hydrodynamic design. A research project steered by Dr. Ignazio Maria Viola shows how CFD can be applied to the design of an America’s Cup yacht. Dynamics 32 - Read more...
Deborah Eppel - CD-adapco While 1D flow simulation software can accurately and rapidly simulate simple tasks, such as long straight runs, they are not adapted to complex 3D geometries such as separators, slug catchers and dry trees. Full 3D Computational Fluid Dynamics (CFD) codes, on the other hand, have the proven ability to accurately predict flow in these situations, although typically at a much higher computational cost. Generating combined 1D/3D simulations promises the best of both worlds: by making it possible to simulate complex systems of piping and equipment at a much higher level...
Fred Mendonça & Prashanth Shankara - CD-adapco Numerical Simulation of Turbomachinery flows are among the most complex computations performed in the world of Computational Fluid Dynamics (CFD). CFD applied to Turbomachinery has come a long way from the inviscid 2D blade-toblade methods of the 1960’s and recent developments have ensured that numerical simulation plays a major role in turbomachinery design.

James Clement, Fred Mendonça - CD-adapco The NASA C3X internally cooled turbine blade is a well documented case for validation of Conjugate Heat Transfer (CHT). The following analysis demonstrates two key features of STAR-CCM+: multi-domain polyhedral meshing, which automatically builds continuous meshes between the solid, external and internal flow volumes, and transition modeling, which enhances the predicted heat transfer distribution, especially on the blade suction side.
