We have provided a detailed numerical model for simulating flame propagation in a premixed counterflow configuration. It is an unsteady state, one-dimensional model based on the heat and mass balance equations. Attention is focused on the impact of the non-dimensional numbers namely Lewis number, Damkohler number, and Zeldovich number on the flame temperature profile. Also, we have explored what happens when we continue the solutions for higher heat losses. It was found that with increasing the Lewis number the flame temperature decreases, while a further increase in Lewis number results in constant value of the flame temperature. Model predictions have been compared with available data from the literature, which have showed fully good agreement.
