Quickstart¶
This quickstart guide will provide instructions for new users to run small cases with DINO.
These cases are provided in the $DINO_HOME/WORK/TESTS directory and aim to help new users understand the setup of a DINO simulation.
The quickstart guide focusses on three different cases, that incorporate different levels of detail, going from zero-dimensional cases to a fully reactive three-dimensional one. Available cases are:
0D Auto Ignition Test Case¶
The auto ignition test case is a small, 0-dimensional simulation of a hydrogen-oxygen mixture at atmospheric pressure and a temperature of \(T=1075.5\) K. This high temperature ultimately leads to an ignition after a certain time, that is prescribed by the reaction kinetics of the respective mixture, the so called ignition delay time (IDT). It is a common practice to test chemical mechanisms with these "perfectly stirred reactor" simulations, that model a homogeneously mixed fuel oxidizer mixture at given thermodynamic conditions.
In general, the level of detail of a kinetic scheme, given its incorporated species and reactions, determines its accuracy and computational cost. In the simulation of reactive flows, different types of mechanisms are distinguished absed on their level of detail:
- Detailed mechanisms:
- Skeletal mechanisms:
- Global mechanisms:
