In this study the effect of boundary condition on premixed methane-airstationary Bunsen flames has been experimentally investigated. Laminar burning velocity is calculated by the concentrated cons method (CCM) and Schlieren photography technique, under the effect of laminar boundary horizontal stream air bulk with a range of air flow speeds. The experimental results have shown that the effect of these boundary conditions in general is small on calculated burning velocity if air flow speed is around between (0-50 cm/s). So, it is suggested thatthis effect be neglected. This effect so characterized increases at/around Stoichiometric ratio flames because of the increase of temperature difference between flame and boundary. The results of the experimental findings were compared with the latest published work and showed a good agreement with it, with a maximum discrepancy of (±2.5% at j =1.1).
