This paper presents the computational fluid dynamics modelling of a laminar premixed flame. A specific solver named ’rareLTSFoam’ is developed using OpenFOAM ® code. The solver is used to simulate experimental stoichiometric and rich laminar premixed flames. The modelling is carried out for thermal flow and combusting flow cases. The results show that without including radiation modelling, the predicted flame temperature is higher than the measured values. P1 radiation Model is used with sub-models for absorption and emission coefficients. The model using constant values for the absorption and emission coefficients gave good agreement with measurements for the regions close to burner outlet. However, the weighted Sum of Gray Gas model (WSGGM) reasonably predicts the flame temperature as the flame height about the burner outlet increases.
