Extensive code validation has been performed on numerous laboratory-scale and large-scale combustion experiments. Validation is continuous on-going work based on both own and third party performed experiments.
Laboratory-Scale Validations
Example of the validation on combustion experiment at laboratory scale.
Example of the COM3D code validation on combustion experiment at laboratory scale. Experiment was performed in KIT combustion tube of 12 m long with internal diameter of 35 cm.
