This paper investigates how the streamwise surface temperature variations modify the combustible boundary-layer flows along inclined hot surfaces. The governing equations for reacting boundary-layer flows under natural convection are reduced to a system of dimensionless equations. These equations have been solved using the finite difference method. Numerical results demonstrate that the momentum, thermal, and concentration boundary layers significantly increase owing to the increase of the angle of inclination. It is found from the isotherms that there develops a near-wall layer embedded within the main boundary layer. This maintains an overall thickness for higher values of the streamwise distance. Because of the increase of the amplitude of oscillation, the thermal and concentration boundary layers become thick while the momentum boundary layer becomes thin. In addition, the wall shear stress and the rate of heat transfer are found to increase for increasing values of the amplitude of oscillation.
