Wim De Malsche) and the Mesa+ Institute for Nanotechnology (co-supervision of Prof. This is a joint project between the Free University of Brussels (supervision of Prof. de Malsche et al., (2007), Integration of porous layers in ordered pillars for liquid chromatography, Lab Chip, 7, 1705-1711 SEM images of a porous shell micro pillar array as part of a microfluidic system for separation by chromatography. In the second stage of the project, co-operation takes place with a PhD student who will implement the developed technology for microfluidic applications such as chromatography, a field wherein this developed technology will be key to increase the separation performance by orders of magnitude. Devices are studied, designed and manufactured in the cleanroom. The achievable flow configurations are studied by computational fluid dynamics simulations as well as experimentally with a microscopy setup and in-house developed detection. Unique flow profiles are generated in confined spaces, capable of enhancing mass transfer and minimizing dispersion. This leads to a level of CPU performance scaling that I don't even see on supercomputers.This project has both an experimental and a modeling character, comprising an experimentally study of the electrical properties of modified silicon surfaces and the impact on electroosmotic flow behavior and mass transfer. Unsurprisingly, he seems impressed: "We know from Apple's specs and marketing materials that the M1 Ultra has an extremely high 800 GB/sec memory bandwidth and an even faster 2.5 TB/sec interface between the two M1 Max chips that make up the M1 Ultra, and it shows in the CFD benchmark. Spalart has estimated that if computer performance continues to increase at the present rate, the Direct Numerical Simulation (DNS) for an aircraft will be. He had to double the x-axis just to fit the M1's performance in. Unlike simpler benchmarks that tend to make CPUs look good, the CFD benchmark stresses the entire system and shows us how things hold up as conditions become more and more challenging." With just 6 cores, the Mac Studio's M1 Ultra surpasses the 2019 Xeon before literally going off the original chart. It's what makes parallel CFD computations such a great real world benchmark. This happens because the computational work begins to saturate communications on the system as data and MPI instructions pass between the cores and memory, creating overhead. Thus, CFD has become an important tool for the design, optimization and evaluation of blood pumps. (), a hot Newtonian fluid is extruded from a point source onto a horizontal plane and allowed to cool to the ambient air temperature. Compared with bench and in-vivo testing, computational fluid dynamics (CFD) is flexible and inexpensive, offering the possibility to predict hemodynamics and mechanical blood damage in a purely numerical manner. In this benchmark, previously defined as BM3 by Cordonnier et al. The fourth benchmark adds complexity by introducing temperature to the viscous flow. Some of the results are discussed in the present work in framework of SOLIDWORKS Flow Simulation’s V&V methodology and classifications. Freitas, 1995 Fluid Dynamics Databases, 2002). He has this to say about why he thinks CFD benchmarks are a good test: "As shown above, we see a pretty typical trend where machines get less and less efficient as more and more cores join the computation. Benchmark C (BM-C): Cooling, isoviscous axisymmetric flow. And now DixieFlatline (Slashdot reader 5,077) describes Hunter's latest experiment: Craig Hunter has been running Computational Fluid Dynamics (CFD) benchmarks on Macs for years-he has results going back to 2010 with an Intel Xeon 5650, with the most recent being a 28-core Xeon W from 2019. host of analytical and benchmark solutions as well as on experimental results available from publications and databases (e.g. And now Dixie_Flatline (Slashdot reader #5,077) describes Hunter's latest experiment:Ĭraig Hunter has been running Computational Fluid Dynamics (CFD) benchmarks on Macs for years-he has results going back to 2010 with an Intel Xeon 5650, with the most recent being a 28-core Xeon W from 2019.
