Constant volume method of determining laminar burning velocity suffers from the limitation that correction for flame stretch of such flames is difficult. For this reason, the constant pressure method is more widely accepted as an accurate method for determination of laminar burning velocity and not constant volume method. In the present work, a stretch correction method has been proposed to get the unstretched laminar burning velocity by carrying out numerical simulations for combustion in a constant volume bomb using a constant volume method. Also, three analytical models for burned gas mass fraction have been assessed by comparing them with numerical results to select the most accurate analytical model to relate burned gas mass fraction to pressure. Unstretched laminar burning velocity of CH4–air mixture at pressures up to 4 bar has been obtained using constant volume method, and the results have been validated against literature. Luijten’s model for burned gas mass fraction was found to be the most accurate amongst the ones investigated.
