Stephen Ferguson - CD-adapco STAR-CCM+ is a “no-compromise” solution for modeling problems in electronic cooling, allowing you to account for the influence of multiple length scales when performing cooling scenarios. However, with length scales in a typical problem scaling 11 orders of magnitude (from transistors a 10-9m to datacenters at 102m), it is neither sensible nor prudent to include them all in a single model.

Ruben Bons - CD-adapco STAR-CCM+ is one of numerous software tools that can be used for electronics thermal management simulations. Even if we narrow our focus to only 3D CFD simulation software, there still are quite a few. And I think it is fair to say that on the whole the tools do a good job. Inevitably this leads us to ask why companies use STAR-CCM+ for electronics thermal management analyses instead of any one of the others. Electronics Special Report - Read more...
Tobias Linke, University of Hannover. Transverse flows from lateral water discharges into waterways, for example those caused by storm water outfalls, may cause passing ships to drift. In order to provide traffic safety, such effects need to be restricted so that outfall structures create well-balanced flow fields of low intensity. Marine Special Report: Read more...
When Delmar Systems wanted to perform a design validation of the world’s largest suction pile anchor system, they called upon the expertise of CD-adapco. These anchors are used to “park” and anchor large offshore structures such as mobile drilling units. Marine Special Report: Read more...
Stephen Ferguson, CD-adapco. Current design standards require that platforms be built to survive so-called 100-year storms, which generate wave heights of up to about 70 feet. However, during Hurricane Ivan peak wave heights of over 90 ft were measured (including one that severely damaged the Chevron Petronius platform) consistent with a once in 2500-year storm. The problem is compounded by the fact that many of the 4000 platforms operating in the Gulf of Mexico were designed before 1988, when the current 100-year design standards came into operation (although some of the destroyed platforms...
Tomasz Bugalski, Ph.D and Marek Kraskowski - Centrum Techniki Okrêtowej. For most of the competitors at the 2008 Beijing Olympic Games, the possibility of mounting the podium to claim an Olympic medal represents the very pinnacle of sporting achievement: usually the payoff of many years of blood, sweat and tears. However, in 2008, being the best athlete is not longer necessarily enough: in most events the Gold Medal winner will also have had the aid of the very best sporting equipment.

Stephen Ferguson, Consultant Engineer, CD-adapco. To become an Olympic Rowing champion you need two qualities in fair measure: grace and guts. More than any other sport, rowing combines sheer explosive power with fine technique. With winning margins measured in just tenths of a second, Gold Medals are traditionally won by working harder and suffering more than your opponents. At the last two Olympics, however, those rules have changed; blood, sweat and tears alone are good enough. Nowadays, the best teams have another weapon in their armory. At the Olympics, Computational Fluid Dynamics could...
Rodrigo Azcueta, Cape Horn Engineering. Let’s start with the basics. The race consists of 11 ocean Legs, 8 Inshore Races and 8 Pro-Am Races. All up, the boats have to sail about 39,000 miles on their trip around the globe. The race was originally known as the Whitbread Round the World Race and occurred for the first time in 1973.

Rodrigo Azcueta, Cape Horn Engineering. At Cape Horn Engineering we have forgone traditional towing tank and wind tunnel tests in favor of an exclusively CFD-based design philosophy. Using STAR-CCM+ simulations are cheaper, faster and more reliable than traditional tests. We run all simulations at full scale which eliminates the inherent error in scaled test results. Enhanced flow visualization and force decomposition give designers much greater understanding of flow phenomena. Marine Special Report: Read more...
