We have taken part in many professional activities, both nationally and internationally. Topics include combustion science and technology, non-equilibrium turbulence, sprays and droplets, turbulent drag reduction. Several group members belong to a variety of SIGs in the UK-Fluids Network. in the new NATO AVT-344 group on Microtechnologies for Air and Space Propulsion. He is also a member of EPSRC’s e-infrastructure Strategic Advisory Team (SAT).ĭr Prodip Das is part of one of the Faraday Institution’s flagship projects: Recycling of Li-Ion Batteries (ReLiB).ĭr Richard Whalley is involved in a NATO AVT-254 plasma flow control project. Chakraborty is the PI and chair of the UK Consortium on Turbulent Reacting Flows ( UKCTRF) and also a member of the steering committees of the Computational Science Centre for Research Communities ( CoSeC), and UKRI’s Exascale Computing Algorithms and Infrastructures Benefiting UK Research ( ExCALIBUR). These groups belong to the UK-Fluids Network. He is also the co-leader of the Sprays and Droplets, Combustion Science and Technology Special Interest Groups (SIGs). The special issue was devoted to computational analysis of turbulent reacting flows. He is also the editor-in-chief of a special issue of Combustion Science and Technology. Professor Nilanjan Chakraborty was the co-organiser of a workshop on high-pressure combustion. ![]() The group collaborates with internationally renowned colleagues from many leading international organisations. Within the University, we have strong links with various research groups, including: Our research into heat and fluid flow also involves heat and mass transfer in nanofluids and non-Newtonian fluids.and transport processes in fuel cells and Li-ion batteries. We are developing innovative skin-friction drag reduction and flow-separation control technologies. We have developed super-miniature sensors for turbulence measurements. We also investigate turbulent boundary-layer flows and wall-turbulence. Our models lead to greener and more efficient power generation devices. We utilise the advancements of high-performance computing to carry out high-fidelity simulations of turbulent reacting and non-reacting flows involving both single phase and multi-phase fluids.įrom this, we develop models for engineering applications. combusting flows) and non-reacting flows. As a group, we are involved in mathematical, experimental and numerical investigations of turbulent reacting (e.g. Our research activities span the broad area of Thermofluid dynamics.įlows occurring in nature or engineering applications are frequently turbulent. This leads to a level of CPU performance scaling that I don't even see on supercomputers.Our group carries out a wide range of research work. 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. Craig Hunter is a mechanical/aerospace engineer with over 25 years of experience in software development. Mac Studio's M1 Ultra Chip Outperforms on Computational Fluid Dynamics Benchmarks Dr.
