Dr. Stefano Toninel

Global technical lead for thermal science, guiding virtual teams of 5-10 analysis and development engineers based on five different sites (US, Germany, Austria, Poland and India) working on the thermal-fluid design of GE Distributed Power’s large-bore reciprocating gas engines for power generation and gas compression (250 kW - 10 MW). Gas Engines | Combustion | Ignition | Spark-plug | Pre-chamber | SCR | Digital Thread | Digital Twins | HPC | Additive Manufacturing | DFSS

Responsible for planning, supervising and reviewing all CFD analyses dealing with the all-round multi-dimensional/multi-scale thermal-fluid modeling of reciprocating gas engines. Cylinder Head Analysis | Methodology Development | Analysis-led Design | Model-to-Make vs. Test-to-Break | Combustion CFD | Thermal Boundary Conditions | Conjugate Heat Transfer | Wall-boiling Modeling | Non-linear FEA | Low-Cycle Fatigue | High-Cycle Fatigue | Thermal Survey

Development and application of CFD methodologies for the design of large-bore reciprocating gas and Diesel engines. CFD | Gas Engines | Diesel Engines | Diesel Spray Modeling | Diesel Combustion Modeling | Spray Optical Diagnostics | Rate of Injection Measurement | Cylinder Head Analysis-led Design | High BMEP | Mixture Formation | Gas Mixer

Responsible for the development and validation of combustion and ignition models implemented in ANSYS CFD simulation software within R&D projects co-funded by automotive manufacturers and the European Union. CFD | Combustion | Ignition | G-Equation | Flamelet Libraries | Geometrical Reinitialization | SAE Journal of Engines | Multi-cycle Intake Simulations | Automatic Meshing | Software Engineering | Agile | Quality Assurance | High Performance Computing | Best Practice Guidelines

Development of NEMO (Numerical Engine for Multi-physics Operator), a new parallel, object-oriented, software for Computational Continuum Mechanics (CCM), demonstrating the capability of the Fortran 95 language to support object-oriented programming for CCM/CFD applications, while preserving the computational efficiency typical of procedural Fortran codes on HPC architectures.
