From our previous reports, it is clarified that the fluctuations in the jet center have an important effect on opposed turbulent jet flow fields. In the jet center, where symmetrical flow fields are characterized, the turbulent structure will be different from those in other parts of the jet. In the turbulent opposed jet center, the fluctuating velocity plays role equal in importance to that of the mean velocity. The momentum which locates the impinging surface comprises three parts: that is, a mean velocity, a static pressure and a fluctuating velocity. The present paper deals with the influences of the variations of the fluctuating velocity, employing the turbulent lattice in the center of turbulent opposed jets, to the locations of the impinging surface.
