Internship | Development and validation of a phenomenological H2 HPDI Combustion Model

About this position

Hydrogen is considered as an important ( fuel for heavy duty combustion engines for mobility and power generation The hydrogen diesel High Pressure Direct Injection ( combustion concept is considered as a feasible combustion concept with high performance potential (power output, load response) This combustion concept is driven by the direct injection of hydrogen which is ignited using a small pilot fuel (e g diesel) injection For engine optimization, fast computing models with predictive capabilities (“phenomenological model”) simulating the HPDI combustion process are desired These models allow performing iterative engine simulations for systematic optimization, engine concept and controls/diagnostics development Main focus is on simulating in cylinder pressure, heat flows and NO emissions Currently, a base H 2 HPDI fuel injector and a H 2 HPDI in cylinder combustion model, built in the Matlab ® environment, are available These models will serve as the starting point of this assignment.

What will be your role?

Objective
Development and validation of a phenomenological Hydrogen High-Pressure Direct Injection Injector and combustion model. Extension of the model with NOx emission formation.

Approach

  • Literature study on HPDI (hydrogen) injection and combustion 1;
  • Get acquainted with the available H2 HPDI injector and combustion model;
  • Linking HPDI injector model to the HPDI combustion model and validating simulation results against measurements;
  • Identify possible model improvements and design, implement and validate solutions;
  • Extend validated H2 HPDI model with NO formation model;
  • Validate H2 HPDI model for NOx emissions using available measurement data;
  • HPDI combustion model sensitivity study towards optimizing efficiency and emissions;
  • Writing reports and presenting results.

What we expect from you

  • Affinity with combustion engines and numerical work
  • Good Matlab modeling skills
