Spend time in the boardrooms or around the water coolers of Houston, and the subject will soon turn to the day’s oil price. Due to a combination of anemic global economic growth and, among other things, the supply side revolution of North American Shale, the oil price has plummeted by almost 30% in the past 3 months. As I write this blog WTI* is trading at a 5 year low, leaving the industry contemplating the considerable challenge of operating at $50 per barrel. While each company’s view on how to tackle this new paradigm will differ, for many it will be to continue the day job (deliver quality, innovative products and solutions), but at reduced time and cost, without compromising safety. It’s my belief that first principles approach, based engineering simulation tools such as those we (CD-adapco) deliver, will be a key enabler, as companies will increasingly rely on simulation based design exploration. The initial driver will be to reduce engineering cost and time, but they’ll also benefit from simulation as an innovation enabler.
Geometry Simplification in Electronics Thermal Simulations: How Much is Too Much?
Two aspects of electronics design present particular challenges for thermal simulations of electronics devices. First, the mechanical (including thermal) portion of the overall design cycle is typically quite short, even as short as a week or two, so simulation results are desired very quickly. Second, electronics assemblies often include many complex individual parts among the hundreds or thousands of total parts within the assembly. Not all the parts are thermally significant but complex parts such as a molded housing or detailed heat sinks are. The needed complexity of parts is...
Canal de Provas Virtual: Como CFD pode auxiliar o seu projeto a atender aos requisitos EEDI sem comprometer a velocidade de operação da embarcação
Em janeiro de 2013, a IMO ( International Maritime Organization ) apresentou o conceito do EEDI ( Energy Efficiency Design Index ) como uma forma de avaliar a eficiência energética de novas embarcações. O objetivo da regulamentação do EEDI é reduzir as emissões de CO 2 . Isso muitas vezes leva projetistas e engenheiros a reduzir o tamanho do motor e, consequentemente, as emissões. No entanto, pode também penalizar as velocidades de operação. Este Webinar irá apresentar como tecnologia de CFD ( Computational Fluid Dynamics ) está sendo utilizada para avaliar e melhorar os projetos de...
Canal de pruebas Virtual: Cómo el CFD puede auxiliar tu proyecto en cumplir con los requisitos del EEDI sin comprometer la velocidad de operación del buque
En Enero de 2013, la IMO ( International Maritime Organization ) presentó el concepto del EEDI ( Energy Efficiency Design Index ) como una forma de evaluar la eficiencia energética de los nuevos buques. El objetivo del reglamento EEDI es reducir las emisiones de CO 2 . Esto obligaría a diseñadores e ingenieros reducir el tamaño del motor (consecuentemente las emisiones) o las velocidades de operación de los buques. En este Webinar se mostrará el uso de la tecnología CFD ( Computational Fluid Dynamics ) para evaluar y mejorar el rendimiento propulsivo de las embarcaciones. Los objetivos son...
It is our pleasure to announce James Bertwistle as the winner of the 2015 CD-adapco Calendar Contest. This year again, contestants from all around the world submitted images of exceptional quality. James’s entry, which represents the Wind Effects around Tall London Buildings, scooped the first prize owing to its beautiful and accurate representation of the impact of CFD in the planning process of man-made structures.
As an engineering educator, do you wonder how to meet the needs of industry today while researching and developing technology for future generations? As a professional, do you stay awake at night wondering if tomorrow’s engineers will be prepared for engineering success on your real-world applications? Countries around the world are forecasting a shortage of engineers in the coming years and there is speculation today’s engineering graduates are lacking the necessary skills and abilities needed to be successful in current and future engineering environments. So, how do we address this...
