Finite reaction rate chemistry in stagnation point flow
Abstract
The use of the double source model of flow near the stagnation point to examine the role of diffusion and chemical reaction rate in chemical reaction flows is discussed. The flow configuration is analyzed, and calculative results are presented. It is concluded that the rate constant is the most important parameter in the problem, and that the length scale is given by the 'size' of the source pair, modified by the ratio of molecular to kinetic diffusivities. The equivalence ratio and differential diffusivities shift the reaction center away from the contact surface.
