Reacting flow fields of an axisymmetric spray combustor with additional air coming from side inlet are studied numerically. The governing equations for the gas phase are solved using the TEACH code modified for the present problem. The liquid phase equations formulated in Lagrangian coordinates are integrated using the Runge-Kutta formula. Turbulence closure is provided by a standard k-ε model. Reaction rate and evaporization rate are estimated by Arrhenius equation or eddy break up model and the Ranz-Marshall formula, respectively. Effect of the side inlet air on the flow field is given particular attention. It is shown that the flame position changes significantly with the side inlet air mass flow.
