In this study, the probabilistic, data driven nature of the generative adversarial neural netw.rks (GANs)w.s utilized to conduct virtual spray simulations for conditions relevant to aero engine combustors. Themodel consists of tw. sub-modules: (i) an autoencoder converting the variable length droplet trajectories intofixed length, low.r dimensional representations and (ii) a w.sserstein GAN that learns to mimic the latentrepresentations of the evaporating droplets along their lifetime. The GAN module w.s also conditioned w.ththe injection location and the diameters of the droplets to increase the generalizability of the w.ole *** training data w.s provided from highly resolved 3D, transient Eulerian–Lagrangian, large eddy simulationsconducted w.th OpenFOAM. Neural netw.rk models w.re created and trained w.thin the open source machinelearning framew.rk of PyTorch. Predictive capabilities of the proposed method w.s discussed w.th respect tospray statistics and evaporation dynamics. Results show.that conditioned GAN models offer a great potentialas low.order model approximations w.th high computational efficiency. Nonetheless, the capabilities of theautoencoder module to preserve local dependencies should be improved to realize this potential. For the currentcase study, the custom model architecture w.s capable of conducting the simulation in the order of secondsafter a day of training, w.ich had taken one w.ek on HPC w.th the conventional CFD approach for the samenumber of droplets (200,000 trajectories).
