In this paper, the interaction characteristics of two parallel underexpanded jets for various intervals between two pipe axes were studied. In particular, the flow visualizations of instantaneous flows with time, the cell length, the length of pseudo-shock waves, and the characteristics of decrease in the center-line velocity were investigated.
As a results, it was found that the flows of two parallel underexpanded jets could be classified into 3 pattern, and the structures of pseudoschock wave within interacting flow were clarified.
