Desenvolvimento de produtos utilizando exploração de design e engenharia avançada
O momento da engenharia de desenvolvimento de produtos no Brasil é específico e peculiar. Por um lado, o mercado está retomando o crescimento e necessidade de se diferenciar dos concorrentes é iminente. Por outro lado, o cenário recente resultou em redução dos recursos e engenheiros capacitados. A pergunta agora é: como desenvolver um produto inovador que me diferencie dos concorrentes com os poucos recursos existentes da minha empresa? A resposta passa pelo fato de que falta de recursos não se resolve com mais recursos e sim com estratégia. Neste Webinar, os especialistas da Siemens vão...
How simulations improve performance of transmission systems
Transmissions and axles include gears, bearings and shafts to transmit power from the engine to the wheels. Under stress, these parts can become damaged or degrade due to heat caused by friction. With decreased amounts of oil used to reduce churning losses, there is the potential risk of overheating. Simulations can be used to guide oil to critical regions to minimize heat losses and maximize transmission performance. In test rigs, it is difficult to visualize the flow inside the box for optimizing the flow patterns. Through the use of computational fluid dynamics (CFD), the mixture of air...

You’ve been there; we’ve all been there. Can’t sleep in the early morning hours, turn on the TV and bam, there’s an infomercial that touts a product as the do-everything solution you’ve been waiting for your entire life. This isn’t an infomercial. And we’re not offering something that will turn off your lights before you jump into bed or teleport you home ahead of rush hour traffic. But this is something that, as a process engineer, will make your life a whole lot easier. Admixtus is a Virtual Product Development Tool that seamlessly integrates with our industry-leading engineering simulation software tool STAR-CCM+® to create geometries, set up CFD simulations, and carry out analysis of stirred vessels. Admixtus automates your workflow to set up a simulation from CAD geometry to analysis in a few simple steps. Pretty cool, right? Even better, Admixtus is a great tool for students to learn about mixing in industrial scale systems. Perhaps best of all, Admixtus does not have any additional costs associated with it. Check out more on Admixtus and how it can change your engineering life by helping you overcome annoying design hurdles by registering for our upcoming complimentary global webinar, “Admixtus is the time and cost saving solution for process development engineers” to be held on December 9, 2016.The webinar will also cover multiphysics aspects such as using Discrete Element Modeling (DEM) for solids suspension, Fluid Structure Interaction (FSI) and modeling reactions in the fermentation process.
Don’t worry, this blog has nothing to do with politics. Instead I wanted to spend some time trying to understand the lessons that we as engineers can learn from the failure of the prediction community to successfully forecast the outcome of the 2016 Presidential Election. For me this was an important backstory to the 2016 campaign: the pre-election poll predictions were wrong by a significant enough margin that they completely failed to forecast the outcome of the election. “What does this have do with engineering simulation?” I hear you ask. The answer, I think, is “a great deal.” CFD engineers, like psephologists*, are also interested in making predictions about the future. Whereas Silver and his peers use statistical inference (from opinion polls and other data sources) to try and predict how people will vote in an election, we use numerical models of physics to predict the future performance of a proposed product or design.
If you pack too much matter into a small space, you are likely to get some undesirable consequences as anyone vacationing with small kids will be all too aware. If you have to sit on your suitcase to get it closed, you are likely to be greeted by the sight of your holiday clothes circling on the carousel at your destination. Similar consequences befall the engineer simulating two-way coupled fluid-particle systems when they overload cells in the CFD mesh with too much DEM matter. I refer, of course, to the previous requirement that a DEM particle must be smaller than the flow cell it occupies for two-way coupled simulations. This limitation is due to the way the effects of the DEM particle are applied purely to the flow cell in which the particle centroid lies, and not to adjacent cells that are also overlapped by the particle. When DEM particles are larger than the cell, this results in large sources of momentum and energy being applied to individual cells causing instability and divergence. However, it is not just stability that can be compromised, but also accuracy, with the void fraction of the particle not being fully accounted for if the volume of the cell is smaller than the particle. In practice, this rendered some applications impossible to simulate as geometrical features forced the mesh size to be smaller than particles. The recent release of STAR-CCM+® v11.06 changes all that with DEM source smoothing…
Designing ships for future challenges – a paradigm shift in vessel design
To many companies within the marine industry, it is becoming clear that the combined effect of tackling climate change and the increasingly competitive market landscape requires new and innovative products and business models to be delivered at an ever-increasing pace if they are to survive and secure long-term prosperity. Amplified by the downturn in oil prices and the global economy, companies – both new and old – find success or failure based on how they adapt and respond to these circumstances. This webinar will demonstrate how using simulation in new and deliberate ways is helping...
