Furthermore, the geometry of the fan and the main dimensions of the experimental setup are available as an IGS (initial graphics specification) as well as a Parasolid file.Ĭonsidering low pressure axial fans, main contributions to the current state of the art have been made by several authors but are not limited to them. Experimental data is available on the platform, including the aerodynamic performance of the fan, fluid dynamic quantities, and sound measurements. The used generic fan benchmark case has been recently issued by the European Acoustics Association under the name “A Benchmark Case for Aerodynamics and Aeroacoustics of a Low-Pressure Axial Fan”. Therefore, benchmarking computational schemes is of outermost importance and requires sound data. Modern sound design and sound optimization require robust prediction of aerodynamics and aeroacoustics using numerical methods.

Finally, both acoustic sound propagation models are compared to the measured sound field data. The analysis of the source term structures shows a strong correlation to the sound pressure spectrum. During the validation, good agreement has been found with the efficiency, the wall pressure sensor signals, and the mean velocity profiles in the duct. Thereby, we focus on the turbulence modeling of the flow simulation and mesh convergence concerning the complete aeroacoustic workflow. * Corresponding author: contribution benchmarks the aeroacoustic workflow of the perturbed convective wave equation and the Ffowcs Williams and Hawkings analogy in Farassat’s 1A version for a low-pressure axial fan.

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. 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. 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. 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.
