ddtfoam online with Winfy

We have hosted the application ddtfoam in order to run this application in our online workstations with Wine or directly.

Quick description about ddtfoam:

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.

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
