摘要	The 4 different kinds of guide vanes airfoil turbines are used as objects, and under the same dimensions of the turbine wheel (high-pressure side diameter, low-pressure side diameter, and blade width of inlet, outlet placement angle and number of blades) and the same design, numerical simulations were performed for turbines by using software FLUENT 6.3. The experiment shows that the blade pressure surface and suction surface pressure is low when the hydraulic turbine installations were added standard positive curvature of the guide vane and modified positive curvature of guide vane .Therefore, the efficiency of energy recovery is low. However, the pressure of negative curvature guide vane and symmetric guide vane added on hydraulic turbine installations is larger than that of former ones, and it is conducive to working of runner. With the decreasing of guide vane opening, increasing of inlet angle, flow state gets significantly worse and obvious reflux and horizontal flow appeared in blade pressure surface. At the same time, the vortex was formed in Leaf Road, Leading to the loss of energy. © 2012 Published by Elsevier Ltd.
