Overview

Randomized trial demonstrates improved heat transfer predictions in diesel engines, suggesting enhanced thermal management.

Key Points

  • The objective is to develop an improved CFD wall heat transfer model to enhance prediction accuracy for diesel engine pistons.
  • Utilized 3D-CFD simulations to analyze heat transfer phenomena in diesel engines.
  • Validated local heat-flux predictions with fast-response surface thermocouples on engine pistons.
  • Conducted a theoretical and numerical analysis of existing heat transfer formulations to identify inconsistencies.
  • The proposed three-layer heat transfer model improved prediction accuracy significantly compared to existing models.
  • Experimental data revealed notable discrepancies in heat fluxes across piston locations under various conditions.
  • The new model successfully accounts for spatial variations in near-wall flow fields generated by spray.
