A three-dimensional numerical model is developed to clarify the structure of the converging jets in a triple torch plasma system. Three individual argon plasma jets, issued into atmospheric argon, are mixed with given angle of convergence and form a converged plasma jet. Predicted results show that thermo-fluid fields of the converging plasma jets are symmetric with three symmetric sections at an interval 120°. Symmetry and uniformity of thermo-fluid fields increase with decreasing angle of convergence. Temperature field is more sensitive to angle of convergence than the velocity field. Symmetry of thermo-fluid fields is improved in downstream direction. A dip in the velocity fields corresponds to poor mixing and diffusion of velocity fields of three individual plasma jets. Central gas injection decreases converging jets temperature significantly.
