The enhancement mechanism of mixing and reaction in non-steady chaotic mixing and reaction processes has been discussed in detail experimentally, analytically and numerically, taking into account the three dimensional structure. The mixing pattern is visualized by PLIF method. The three dimensional mixing pattern is visualized by using PLIF images. The estimation method of mixedness by using characteristic widths of advective mixing and molecular diffusion, and concentration variation are proposed.
