Direct injection spark ignition (DISI) has the potential to reduce specific fuel consumption and therefore, mitigate emissions of state-of-the-art internal combustion engines. Thus, the purpose of this project is to resume the work developed under the FAPESP PhD Grant No. 2015/10299-9, in which, as previously reported, a variety of simulations of the Engine Combustion Network (ECN) Spray G evaporative gasoline injection test case have been performed and validated, whereas further spray and engine simulations are scheduled. As a next step, the authors intend to add the previously studied spray models into the solver developed during the grantee's Master studies, while at the University of Duisburg-Essen, in Duisburg, Germany. This code, designed to simulate conventional gasoline engines in motored and fired conditions, is based on OpenFOAM and successfully predicted the flow and combustion processes of the Duisburg Engine (JANAS et al., 2015). Hence, with the additional Lagrangian modules, the authors aim to perform high quality 3D LES simulations of the flow and all other involved physical phenomena occurring inside of a research gasoline direct injected (GDI) engine, such as mixture formation and combustion. However, as the current computational and laboratorial resources at FEG/UNESP are limited, the grantee, endorsed by the local and foreign advisors, is requesting a BEPE scholarship to perform the mentioned activities during the period of 1 year at the Multi-phase Flow Simulation Laboratory of the University of Massachusetts, in Amherst, MA, USA. The choice for this group was due to vast experience of Prof. Schmidt in the field of multiphase flow simulations and the excellent resources of his laboratory. (AU)
