I belong to the Rocky ACE Team and work with simulation of bulk material flows, free surface and particuladen flows. I interface with consumers and commercial partners, for Ansys Rocky pre-sales and post-sales, as well as interlocking with R&D teams, ranging from release testing, customization with APIs, defect reporting and improvements.

• Knock is an undesirable combustion event that may damage spark ignition engines. As a local phenomenon, it is hard to predict.• An ignition delay time (IDT) correlation has been obtained via successive multiple linear regressions through an automatized Python approach based on a database of relevant transportation fuels.• Computational fluid dynamics (CFD) simulations of gasoline direct injection (GDI) engines were performed in AVL Fire. The flow and species quantities of… Show more • Knock is an undesirable combustion event that may damage spark ignition engines. As a local phenomenon, it is hard to predict.• An ignition delay time (IDT) correlation has been obtained via successive multiple linear regressions through an automatized Python approach based on a database of relevant transportation fuels.• Computational fluid dynamics (CFD) simulations of gasoline direct injection (GDI) engines were performed in AVL Fire. The flow and species quantities of spheres on the top dead center were exported to Python to determine the Livengood-Wu integral for knock onset.• Overall, the results based on the IDT correlation proved to be better than other correlations and detailed chemical kinetics, which are more computationally expensive.

Apex Rocketry is a team founded by me and some colleagues at the Federal University of Santa Catarina (UFSC). 1) CFD study of the engine nozzle:• The convergent-divergent angles of the rocket nozzles influence the motor's thrust curve but the current state-of-the-art does not provide concrete answers on the ideal dimensions. • The research compared the current nozzle design's thrust curve generated in MATLAB with CFD simulations in Ansys Fluent, varying either the convergent or… Show more Apex Rocketry is a team founded by me and some colleagues at the Federal University of Santa Catarina (UFSC). 1) CFD study of the engine nozzle:• The convergent-divergent angles of the rocket nozzles influence the motor's thrust curve but the current state-of-the-art does not provide concrete answers on the ideal dimensions. • The research compared the current nozzle design's thrust curve generated in MATLAB with CFD simulations in Ansys Fluent, varying either the convergent or the divergent nozzle angle, totalling 12 new designs.• The results showed that there is not an optimum design but some options better than the baseline. The designs should prioritize the conversion of static into dynamic pressure to increase thrust.2) Training of new members and knowledge management • The study above allowed training three members with MATLAB, Ansys Meshing, Ansys Fluent and Ansys CFD-Post and integrating the areas of aerodynamics and propulsion. • The process was documented through videos demonstrating the use of computational tools to preserve knowledge in the team. • In addition, the study generated publication and presentation of a paper at COBEM 2021.Awards: 3rd place in the 1km-apogee solid propulsion category, 4th overall and team spirit award in the 2020 Online Latin American Space Challenge, the first participation of the team on a competition.

MTEE is an automotive turbocharger supplier for vehicle manufacturers in Europe.• Neither the company nor the casting suppliers knew how scroll core shifts in a turbine housing influenced the performance of an automotive turbocharger.• Different scroll core shift geometries were meshed in Altair Hypermesh, simulated in Ansys CFX and post-processed in Ansys CFD-Post to extract quantities of interest for the data analysis. Python was used to apply statistics to correlate the changes in… Show more MTEE is an automotive turbocharger supplier for vehicle manufacturers in Europe.• Neither the company nor the casting suppliers knew how scroll core shifts in a turbine housing influenced the performance of an automotive turbocharger.• Different scroll core shift geometries were meshed in Altair Hypermesh, simulated in Ansys CFX and post-processed in Ansys CFD-Post to extract quantities of interest for the data analysis. Python was used to apply statistics to correlate the changes in performance with the physical phenomena.• The simulations showed concrete performance impacts and recommended new casting tolerances. The statistical approach proved that the methodology could be used regardless of the geometry. Show less
