Abstract:

Law has shown that the analysis of spherical diffusion flames is quite similar to that of counterflow diffusion flames, so that some explanation is needed for devoting a separate lecture to them. There are two good reasons. First, the constant-density approximation has been used throughout these lectures in discussing all but plane flames, so there is room for a problem which does not neglect variations in density. Plane diffusion flames have to be chambered, i.e. the reactants must be supplied at finite locations, which leads to distracting complications. Secondly, the spherical diffusion flame can lead to quite different and unusual responses. These arise in the technologically important application to the quasi-steady phase of fuel-drop burning, when a more realistic boundary condition than the conventional one is used. Author
