The formation of a secondary street structure is seen in the immediate downstream ( 21D–25D) of the triangular and rhomboid cylinder, while it is absent for the circular, square, and inverted triangular cylinder within the domain of the test section (135D). This study observed that the acoustic perturbation influences the location of the transition point at which the primary street transforms into the secondary street.
