Following Seshadri and Williams solution describing the flow field for the opposed jet burner, the analytical solution is given for the flow field of two other burners: the opposed tubular burner and the tubular burner. Under plug flow boundary conditions, it is shown that the stretch rate at the stagnation surface of the opposed tubular burner is k = pi V/(R-2 - R-1) for the case of equal velocities and equal densities (i.e., p(1) = p(2) and V-1 = - V-2 = V). For the tubular burner, the stretch rate at the center of the burner is k = pi V/R-2. The comparison of the numerical simulation and analytical Solution is carried out to verify the analytical solution. (c) 2005 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
