Flame propagation along a fuel-oxidizer contact surface

This paper reviews and considers aspects of flame propagation along the contact surface between layers of fuel and oxidizer in five different systems including gas fuel with air, liquid fuel with air, solid fuel with gaseous oxidizer, solid fuel with liquid oxidizer, and solid fuel with solid oxidizer. Some of the aspects covered include flame velocity along the contact surface, the dependence of flame speed on thickness of the fuel layer, the effect of oxidizer concentration on flame velocity, and the effect of convection. Alcohol fuels and some perchlorate oxidizers are briefly investigated.
