Description

This solver represents an addition to the open-source CFD package OpenFOAM.
The solver is used to simulate the deflagration-to-detonation transition in hydrogen-air mixtures.

Prominent features are described below.

Additional description is available in the pdf file included.

For a more detailed description download Florian Ettner's thesis (in German) from

Features

  • accurate shock capturing with a density based solver
  • deflagration modelling via a reaction progress variable
  • auto-ignition sub-grid model separating each computational cell into a "shocked" and an "unshocked" part
  • auto-ignition from tabulated ignition delay times, gained from a detailed chemical mechanism
  • low computational cost due to applicability to coarse grids and usage of pre-tabulated chemistry
