In the early hours of Saturday May 6, at the Monza motor racing circuit in Italy, Eliud Kipchoge ran 26.2 miles in 2 hours and 25 seconds, beating the existing marathon world record by 2 minutes and 32 seconds. The run was the culmination of Nike’s “Breaking 2” project, a two year program aimed at demonstrating that it is physically possible for a human to run a marathon in less than two hours. Before the run, much of the publicity had focused on Nike’s spring loaded Vaporfly Elite running shoe, which they had claimed improves running efficiency by as much as 4%. However in the days afterwards much of the conversation turned to aerodynamics, and the influence of the unfeasibly large timing board that was mounted on top of the pace car that drove in front of Kipchoge, and the “delta formation” adopted by his team of “relaying” pacers. By some calculations drafting was responsible for about 1:30 of the 2:32 that Kipchoge knocked off Kimetto’s world record. In order to determine just how much influence "aerodynamic trickery" had in getting Kipchoge within 26 seconds of the mythical 2 hour barrier, we decided to run a series of computational fluid dynamics simulations using STAR-CCM+,
Driving innovation with gas & liquid-fuel combustors through CFD and design exploration
Until recently, the ability to accurately characterize combustion of gas-fuels (usually methane) and liquid-fuels required the use of expensive testing and validation. The development of computational methods over the last 20 years has opened the doors to new methods to help engineers discover better combustor designs faster by enabling the accurate assessment of such important combustor performance characteristics as: Fuel/air mixing The ability to use different fuels in the same combustor (or with only slight modifications) Predictions of NOx and CO emissions and soot formation, including...
Ensuring safety during production and maintenance is critical to the oil and gas industry, while operational reliability and production assurance are key to operating a successful oil and gas production facility. This event will explore the role of simulation in two aspects of oil and gas, maintenance and production operations. We will have two presentations: Simulation Engineering: A Virtual Blow-Out Preventer Alistair Gill, Vice President (Advanced Engineering) Wild Well Control, will present how his team uses simulation of pipe freezing to assess how to perform safe mechanical repairs to...
Growing competition and increasing environmental awareness within the marine industry drives a continuous need for more efficient methods for the design of new vessels. Today, CFD is widely used to perform analyses of ship hulls in calm water, yielding results which can be used to quantify important parameters such as calm water resistance or propeller-hull interaction. However, calm water is usually far from the true operating conditions, meaning that understanding the performance in real sea states is of great importance. In many cases, the optimum design for rough seas differs...
Please join us on June 6 for an introduction to STAR-ICE, the exciting new add-on to STAR-CCM+ ® for setting up in-cylinder simulations. Due for first release in STAR-CCM+ v12.06, STAR-ICE represents the transition of modeling your in-cylinder simulations from STAR-CD, allowing you to leverage the many powerful benefits of the STAR-CCM+ platform. This exciting early look at the add-on will inform and prepare you for the impressive next chapter of in-cylinder CFD. In this webinar, we will be covering the following topics: What is STAR-ICE? Transitioning from STAR-CD to STAR-ICE The STAR-ICE...
Improving semiconductor shower head performance with simulation
The shower head is a critical part of a chemical vapour deposition (CVD) chamber, distributing gases properly to ensure uniformity of deposition rates across the wafer. The shower head typically consists of a large number of small holes through which the gas is delivered over the surface of the wafer. Precise control of flow speed, temperature and gas species distribution is critical, so a well-designed shower head provides higher quality deposition as well as increased wafer throughput. This On-Demand webinar will explore the usage of simulation to improve the design of a shower head. The...
Simulações avançadas de CFD aplicadas a projeto e otimização de embarcações
O desenvolvimento de projetos de embarcações tem sido constantemente atualizado com novas tecnologias. A eficiência do navio tem se tornado cada vez mais importante em um mercado onde as margens operacionais são baixas e as normas de emissões estão cada vez mais apertadas. Os proprietários das embarcações são geralmente demandados por tomar decisões rápidas sobre mudanças no projeto ou modificações que afetam a performance. Neste sentido, o tempo de resposta é tão importante quanto a sua precisão, de forma que se possa atender aos prazos apertados no projeto do navio. Para que estes desafios...

Over the past 10 years, bat populations in the United States and Canada have been decimated by an invasive fungus called Pseudogymnoascus destructans, or pd. Millions of bats have died. Considering that they are a keystone species, losing bats and their contributions to our ecosystem could have devastating results for plants, other animals and humans. The epidemic bats are facing is akin to the massive die off of bees that’s a threat to agricultural food supplies. Understanding what is happening to bats as well as the conditions they’re exposed to is essential for us to try and find a way to reverse the epidemic.
Join us for a free engineering workshop where we will present the value of bringing simulation into your engineering process and demonstrate how automated computational fluid dynamics (CFD) and design exploration can help drive innovation and meet modern engineering challenges.
