Since I started my career in an industry in 1949, I had been engaged in research and development concerning experimental techniques as an experimental engineer. In particular, I devised various flow visualization techniques that were eventually employed for development and innovation of such products as Machineries and plants. In 1985, I moved to the present University where I continued to improve flow visualization techniques using a smoke wind tunnel and produced significant results in transferring those techniques to educating. Looking back these fifty three years, I am going to introduce to you results, I obtained from the flow visualization as long as I am allowed.
