The paper presents the numerical investigation of flame characterization of Inverse Jet Diffusion Flame (IJDF) using a circumferentially arranged fuel port (CAFP) burner with the elliptical and circular central orifice. The elliptical orifice helps to enhance the ambient air entrainment compared to the circular orifice. The OH mole-fraction contours are used to visualize the flame shape and jet spread in elliptical and circular inverse jet diffusion flame configurations. The jet spread is found to be broader for IJDF with an elliptical central jet as compared with the circular port. Moreover, higher turbulent kinetic energy in the minor axis plane signifies more considerable air-fuel mixing in elliptical CAFP IJDF.
