Special Issue Information

Dear Colleagues,

The third edition of this Energies Special Issue, entitled ‘Computational and Data-Driven Modeling of Combustion in Reciprocating Engines or Gas Turbines, 3rd Edition’, builds upon the success of the first edition and second edition by further advancing the discourse on the topic. This edition continues to gather cutting-edge research on reciprocating engines or gas turbines.

In the last decade, more stringent regulations have forced a significant reduction in the levels of pollutants emitted into the atmosphere; nevertheless, internal combustion engines and gas turbines still represent the most widely operated energy conversion systems. Experimental investigations play a fundamental role in allowing better understanding and limiting of the processes that are responsible for noxious species formation. Indeed, only experimental activities can provide basic data to deeply analyze the phenomena occurring inside combustion chambers.

On the other hand, experimental facilities require high cost of maintenance and operation and, therefore, the same data can be used in the validation of numerical models. The latter are helpful to predict the behavior of engines and gas turbines under a wide range of operating conditions or to test their operation in innovative combustion concepts.

For this Special Issue, we invite you to submit papers involving combustion computational models and their methodologies of validation, covering a wide range of applications and solutions.

Some of the topics of interest for publication include but are not limited to:

  • Compression ignition engines
  • Spark ignition engines
  • Gas turbines
  • Experimental data processing and analysis
  • Combustion modeling
  • Model validation
  • Computational fluid dynamics
  • 0D/1D codes
  • Innovative fuels
  • Innovative combustion concepts

Papers submitted to this Special Issue will be selected after a rigorous peer review procedure with the aim of rapid and wide dissemination of research results, developments, and applications.

This article discusses the potential of using the double-Wiebe function to model combustion in a compression-ignition engine fueled by diesel fuel or its substitutes, such as hydrotreated vegetable oil (HVO) and rapeseed methyl ester (RME), and hydrogen injected into the engine intake manifold. The hydrogen amount ranged from 0 to 35% of the total energy content of the fuels burned. It was found that co-combustion of liquid fuel with hydrogen is characterized by two distinct combustion phases: premixed and diffusion combustion. The premixed phase, occurring just after ignition, is characterized by a rapid combustion rate, which increases with an increase in hydrogen injected. The novelty in this work is the modified formula for a double-Wiebe function and the proposed parameters of this function depending on the amount of hydrogen added for co-combustion with liquid fuel. To model this combustion process, the modified double-Wiebe function was proposed, which can model two phases with different combustion rates. For this purpose, a normalized HRR was calculated, and based on this curve, coefficients for the double-Wiebe function were proposed. Satisfactory consistency with the experiment was achieved at a level determined by the coefficient of determination (R-squared) of above 0.98. It was concluded that the presented double-Wiebe function can be used to model combustion in 0-D and 1-D models for fuels: RME and HVO with hydrogen addition. Full article
