【Abstract】 The governing equations of the belieal flow of the power-law fluids in eccentric annuli are established and numerically calculated by the finite diference method in this IJaper. Results show that there is a secondary flow in the belieal flow of the power law fluids in Eccentric annuli. Finally,the secondary flow is discussed.更多还原
