Perforated Plates and Other Porous Media: To Idelchik or not Idelchik
Electronics assemblies frequently include perforated plates, louvers, fibrous filters, finger guards and other components with very fine flow passages. The primary purpose of each of these parts might serve aesthetic purposes, provide EMI shielding, dust filtering or ensure user safety, but they also can significantly restrict the air flow through the system. Properly accounting for the added flow resistance they introduce is critical for the thermal design of the electronics. But because these porous media have fine geometric features with small flow passages, it may not be desired — or even...
DARS Basic is GUI-driven and provides a library generation functionality which facilitates analysis of fuel compositions, accurate prediction of knock and emissions for dual fuel engines, exploration of combustion of any fuel or oxidant mixtures and exploration of soot yield for new fuels and new operating conditions.
Using DARS, the product design cycle will be faster and more cost-effective through the prediction and analysis of chemical processes and emission formation before, or as a complement to, experimental testing
Sandia D Piloted Methane Flame
Resolving the flow field of a turbulent flame, including turbulence-chemistry interaction, for a full CFD grid, is extremely CPU expensive. DARS Basic enables simplifcations to carry out the simulations efficiently.
You might have noticed our recent announcement that STAR-CCM+® has “maintained perfect scalability” across 55,000 cores on the 1.045 PetaFLOPS Hermit cluster, at the High Performance Computing Cluster Stuttgart (HLRS). This announcement made me smile for two reasons. The first was that one of our competitors has recently been bragging about running a simulation on 10,000 cores. Well done for that! But, more importantly, because I’ve spent a lot of time recently interviewing the founders of our company for an article that I’ve written about our 35th Anniversary. One of the recurring themes in those interviews was that of computing that they had access to in the early days of the company. adapco’s first computer was a VAX 11/750, described by Steve MacDonald as being “about the size of a washing machine.” This computer, which cost a cool $200k (adjusted for inflation), was capable of performing a massive 120,000 floating point operations per second. VAX 11/750: 1980 supercomputer disguised as a washing machine How does that compare to modern computers? Or even the phone in your pocket?
CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, announced today a new standard in performance and scalability for industrial CFD software. Working in partnership with High Performance Computing Center Stuttgart (HLRS) and SICOS BW, STAR-CCM+® was run on the entirety of the 1.045 PetaFlop Hermit cluster, managing to maintain perfect scalability beyond 55,000 cores.
See the blog on Glass Coating with STAR-CCM+ that describes this simulation. As the layers build up to several centimeters of thickness during the glass coating process, it is important to understand the influence of the coating on the fluid flow. Simulation provides insight into coating behavior as the thickness of the glass changes. The key to simulating glass coating is to modify the geometry of the glass as coating occurs. The process below shows how this can be done easily in STAR-CCM+. Use Overset Mesh around the glass and specify rotation, translation and morphing (with Linear Fitter)...

And so with anticipation, I opened an email from my German colleague, Nicole Vasold, with the words ‘bottle’ and ‘wine’ in the subject line. Maybe she wanted to send me a note about a very belated Christmas gift coming my way? My excitement however turned to horror when I realized the email was all work and no play, or should I say ‘All glass and no wine’? She had shared her latest work on simulating the glass coating process of a wine glass, another addition to the growing use of simulation in the glass manufacturing industry.
