Overview

Demonstrates the combustion behavior of C2H4-O2 using machine learning potential functions, indicating a framework for complex fuel simulations.

Key Points

  • The aim is to accurately model the combustion process of C2H4-O2 using a machine learning potential function.
  • Constructed a reactive machine learning potential function using 890,682 configurations.
  • Conducted molecular dynamics simulations to sample configurations and identify reactions.
  • Assessed the MLP in the NVT ensemble with 100 C2H4 and 300 O2 molecules at 3000 K.
  • Achieved a fitting error of 0.014 eV for the C2H4-O2 MLP.
  • Identified 175 species and 633 reactions, reduced to two simplified networks.
  • Predicted reaction rates align with established combustion mechanisms.
