This case is an example OpenFOAM setup for calculating the Ignition Delay Time (IDT) of TPRF-E chemical kinetic mechanism
The simulation is performed using chemFoam, a zero-dimensional homogeneous reactor solver available in OpenFOAM. The case is configured to evaluate the autoignition behavior of the fuel blend under specified thermodynamic conditions.

Case Description
Solver: chemFoam
Application: Ignition Delay Time (IDT) prediction
Reactor Type: Zero-dimensional homogeneous reactor
Chemistry: Detailed chemical kinetic mechanism with PLOG reactions
Initial Conditions

The example case is configured for:

Initial Temperature: 730 °C (1003.15 K)
Initial Pressure: 10 atm

These conditions are representative of engine-relevant autoignition studies and can be modified by the user for additional validation cases.

Prerequisites

This case requires a custom PLOG library because OpenFOAM does not natively evaluate Arrhenius PLOG expressions. The PLOG support library from Lund University must be installed before running the case. Instructions to this has been given in the 'readme.txt' inside the simulationCase Folder.

Download the library from:

It has to be noted that 0d simulation does not have a dedicated '0' folder. Instead, there is a file known as 'initialConditions' inside the constant folder. This determines the initial pressure, temperature and mole fractions of the various species.
