| Research Abstract |
Vortical structures, chaos and turbulence transition in two-and three-dimensional wakes were investigated experimentally and numerically. At first we conducted a series of experiment of micro-bubble flows through circular straight and helical pipes. Apparent drug reduction and relaminarization were observed, and reduction of thermal conduction was also seen. A new spectral code was written, by using which stationary and oscillating solutions were obtained with high accuracy.
