... to limited insights into their underlying models. Achieving an optimal balance between model complexity, interpretability, prediction accuracy, and computational cost is crucial for cycle-by-cycle control and effective fault-tolerant engine management on advanced RCCI engine platforms. In this study, we...

... aftertreatment systems for meeting upcoming criteria pollutant regulations. High-pressure fuel injection equipment is a key enabling subsystem for GCI and optimization along with the combustion, air and aftertreatment systems requires the use of simulation-based design tools like 1D hydraulic models or 3D-CFD...

... this initial ignition period and activating a larger volume of the fuel-air mixture. This work presents a computational study of spark discharges in high cross-flow ignition environments using a high-fidelity, multi-physics equilibrium plasma solver. The numerical framework is designed to simultaneously model...

... of the spark physics with a finite rate chemical kinetics-based combustion model. A future goal of this proposed framework will be to model and validate a coupled ignition and combustion simulation for spark ignited engines. Two separate solvers are used to model spark physics and combustion kinetics...
