Dacolt has conducted a parametric investigation of the auto-ignition process of a n-heptane / air mixture, using Dacolt PSR.

It demonstrates the use of Dacolt PSR for studying auto-ignition behavior in Diesel engines, for example. The case study consists in the following steps:

1. Set-up and executing Dacolt PSR simulations for different initial conditions of equivalence ratio, temperature and pressure
2. Automated post-processing of the Dacolt PSR results, to determine the first and second ignition delays
3. Analysis of the resulting ignition data
4. Export of the ignition data to a CFD look-up table, to include in CFD simulations (optional)

These steps are described in detail in the case study "auto-ignition analysis with Dacolt PSR". The resulting datasets can also be viewed directly on our website:
