This work deals with the numerical solutions of combustible boundary layer flow over an axisymmetric body. A mathematical structure is taken out by explaining the governing equations of continuity, velocity, energy and concentration. These are solved employing the finite difference technique. The nature of the flow is analyzed using velocity, temperature and mass concentration for different physical parameters such as, surface location, Prandtl number, Schmidt number, viscosity variation parameter, thermal conductivity parameter and the radiation parameter. It is found that the viscosity variation and thermal conductivity parameter augment the thicknesses of thermal and concentration layers and reduces the momentum thickness. Moreover, the momentum, thermal and concentration boundary layers become thick for larger values of radiation parameter whereas the reverse characteristic is observed for higher value of the Prandtl number.
