Accelerating Decarbonization of Transportation and Power Generation Sectors: Leveraging Leadership..

Combustion Webinar Sep. 7, 2023; Speaker: Sibendu Som
This is an opportune moment to tackle some previously computationally intractable research questions by leveraging leadership computing and AI techniques. Next-generation spectral element based highly scalable Nek code for Direct Numerical Simulations and wall-resolved Large Eddy Simulations when fused with unique experimental measurements from Advanced Photon Source at Argonne, enable us to develop better understanding and improve models for propulsion and power applications. Several examples of the above approach will be discussed related to piston engines and gas turbines, for e.g., liquid and gaseous jets in vitiated cross flow, liquid film cooling, lean blow-out, high-altitude relight, etc. New insights gained from high-fidelity simulations will be discussed which lead to more accurate device level simulations and optimization using CONVERGE CFD code will be shown.  
Dr. Som is Director for Advanced Propulsion and Power Department at Argonne National Laboratory. He has more than a decade of experience in modeling and simulations of propulsion, power generation, and manufacturing processes on HPC systems. His team develops predictive simulation capabilities using unique experimental diagnostics at Argonne for advanced high-efficiency low-emission power and propulsion systems. He is a co-founder of Argonne’s Virtual Engine Research Institute and Fuels Initiative program which is aimed at providing predictive simulations for OEMs. Dr. Som has authored more than 170 journal and peer-reviewed conference papers and 6 book chapters.
