A theoretical investigation of the influence of a standing wave flow-field on the dynamics of a laminar two-dimensional spray diffusion flame is presented for the first time. The mathematical analysis permits mild slip between the droplets and their host surroundings. For the liquid phase, the use of a small Stokes number as the perturbation parameater enables a solution of the governing equations to be developed. Influence of the standing wave flow-field on droplet grouping is described by a specially constructed modification of the vaporization Damkohler number. Instantaneous flame front shapes are found via a solution for the usual Schwab–Zeldovitch parameter. Numerical results obtained from the analytical solution uncover the strong bearing that droplet grouping, induced by the standing wave flow-field, can have on flame height, shape, and type (over- or under-ventilated) and on the existence of multiple flame fronts.

It has been demonstrated that the addition of N2, CO, Ne, Ar, Kr, Xe, CO2, and CF4 to a H2-air diffusion flame containing He and traces of CH4 enhances the level of ion formation. This enhancement is proportional to the concentration of both CH4 and the diluent gas, consistent with the proposition that the diluent gas participates in the ion formation process.
