Two-dimensional transient simulations of premixed hydrogen–air flames in a converging–diverging microscale tube have been performed in the present study. The effect of various thermal wall boundary conditions on flame dynamics is realized. Different flame shape transitions are observed with a change in the flame propagation speed, flame temperature, and heat release rate for different wall heat transfer coefficients. This progression of flame behavior is attributed to the thermal wall coupling and hydrodynamic effect.
