The increasing demand to reduce the consumption of fossil fuels and also of carbon dioxide emissions is fueling the research for alternative approaches to energy generation. Using trapped-vortex technology to burn syngas in gas turbine burners potentially offers several advantages over other approaches: it makes it possible to burn a variety of fuels with medium and low calorific values; the NOx emissions have very low levels without dilution or post-combustion treatments; it provides extended flammability limits and improves flame stability. The systems used so far generate a pilot flame by means of combustion in cavities to create premixed high-speed flows. This technical article presents a study to design a device that operates entirely on the principle of trapped vortices that intrinsically improve the mixing of hot combustion gases with fresh mixture, a characteristic that is essential both to diluted combustion and to Moderate or Intense Low-oxygen Dilution (MILD) combustion.

The text provides an in-depth account of Stefano Odorizzi’s journey in founding and growing EnginSoft, our engineering company specializing in computer simulation and modelling. Established in 1984, EnginSoft overcame early challenges, such as the high cost of computing, to emerge as a leader in simulation services, particularly in the fields of mechanical engineering and computational fluid dynamics (CFD). The narrative highlights several key milestones in the company’s history.
