Overview

Numerical analysis shows flame propagation and temporal characteristics of hydrogen jet ignition in combustion engines, indicating optimal pressure and temperature settings.

Key Points

  • Higher injection pressure delays jet flame formation, extends duration, and increases peak temperature and heat release rate.
  • At 2.5 MPa, optimal pressure enhances jet flame stability, whereas 700 K accelerates formation but shortens duration.
  • Computational fluid dynamics model simulates flame characteristics under varying pressure and temperature settings.
  • Findings may optimize hydrogen jet ignition systems for improved performance in internal combustion engines.
