Overview

Novel predictive model improves energy conservation in marine engines, leveraging CFD simulations and 3D particle image velocimetry.

Key Points

  • This research aims to develop a predictive model for uniflow scavenging in marine diesel engines to enhance efficiency and reduce emissions.
  • Developed a predictive model based on Taylor vortex for scavenging performance.
  • Conducted high-speed 3D particle image velocimetry to analyze velocity fields.
  • Performed computational fluid dynamics (CFD) simulations to evaluate scavenging efficiency.
  • Developed a dual-zone scavenging model predicting residual gas distribution with ±3.5% accuracy against CFD results.
  • Identified that scavenging port angles and engine load affect vortex dynamics and exhaust residuals.
