The objective of this work is to develop an efficient emulator framework using modern machine learning techniques to predict spatiotemporally evolving flow dynamics for design exploration. This emulation framework encompasses autoencoders for nonlinear dimensionality reduction, deep neural networks for regression and predictive modeling, and a reconstruction algorithm for recovery of the flowfields. As a demonstration case, the turbulent multiphase flow development in a side-oriented single-hole diesel injector is considered for a wide range of design parameters, fuel properties, and operating conditions. The prediction accuracy of the flow features for new design settings is assessed, and the efficiency of the proposed emulator is evaluated.
