Overview

Examines wall-impingement characteristics of diesel/methanol dual-fuel sprays, highlighting complex interactions in high-pressure environments.

Key Points

  • The study aims to clarify the effects of wall-impingement characteristics and flow dynamics of diesel/methanol dual-fuel sprays in marine engines.
  • Utilized shadowgraph imaging for visual analysis of spray dynamics
  • Conducted quantitative analysis of spreading radius and uplift height
  • Tested varying impingement distances and angles in a constant-volume chamber
  • Larger impingement distances promote vapor formation and atomization post-impact
  • Higher impingement angles enhance spray deflection and alter gas-phase dynamics
  • Impingement angle has a stronger effect on spray dynamics compared to methanol alone
