Jean-Philippe Pélaprat - ORECA, France The aerodynamic configuration of a Le Mans Prototype depends on the nature of the track where it races: some pre-installed parts may be adjusted, such as the rear wing main plane or the flap. Regulations permit the homologation of various versions of the aerodynamic package but place restrictions on how many changes can be made. Typically, up to two “flaps” are allowed to be added on the front fenders in order to increase the front downforce. These flaps are the object of the aero analysis and optimization described in the article. Dynamics 31 - Read...
Flavio Cimolin, AMET S.r.l, Andrea Menotti, Olsa S.p,A, Lucia Sclafani, CD-adapco The design of rear lamps for the automotive industr y is becoming more challenging as an ever finer compromise between product lightness and resistance to heat loads needs to be found. Only after engineers have successfully achieved this delicate but essential balance, style and aesthetics considerations can be added to the equation. Dynamics 31 - Read more...
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...

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.
