Flowfields resulted from interaction of two equivalent freejets issued from two parallel two-dimensional sonic nozzles at various nozzle distances and at various values of the stagnation to ambient pressure ratio are investigated numerically and by visualization. A strong shear flow region appears between the two jets, which is observed by visualization, is simulated well by the present calculation. Agreements of the parameters representing the whole structure of the flowfield, such as the location of the interaction point of the inner lateral shock with the outer one, the location of the shock reflection point on the symmetry plane and the deflection angle of each jet by interaction, are very well between the simulation and the experiment so far nearly two-dimensional flows are realized in the experiment.
