Joseph Kummer and JB Allred, Propulsive Wing LLC Airborne allergens and contaminants found in public places have been proven to have an adverse effect on people, such as a reduced productivity at the workplace, an increased exposure to diseases on airplanes, unhealthy learning environments for children, and sometimes the occur rence of secondary infections in hospitals. One potential solution is the use of personal air ventilation systems, or PAVs. Dynamics 31 - Read more...
Matthew N. Godo, Ph.D., FieldView product manager, Intelligent Light In the world of CFD simulation, maximizing retur n on investment comes not just from reducing the cost of analysis while increasing output, but from fully mining that output for critical insight and accurate answers. STAR-CCM+ and STAR-CD users are well aware of the many benefits these power ful and popular solver codes bring to the design and engineering process, including the ability to solve complex, lar ge data problems. If analyzing that data can’t be done ef ficiently and ef fectively, however, the investment in those...
The last decade has seen an increased interest in the development of Unmanned Aerial Vehicles (UAVs) and their applications which are no longer restricted to the military field of operations. UAVs - either remotely piloted or fully autonomous - provide a safer, cheaper alternative to larger, piloted aircraft, as well as a valuable ‘bird’s eye’ observation platform mid-way between ground-based sensors and high-flying satellites.

Steve Hartridge - CD-adapco Since our collaboration was announced last year, the development teams of both CD-adapco and Battery Design LLC have been working hard to bring this exciting project to fruition. The principal objective of the project is to deliver a tool that will allow engineers to simulate flow, thermal and electrochemistry within a single code. Dynamics 31 - Read more...
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...
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...
