N2 - A butterfly valve attached at downstream of an elbow is inspected at Reynolds number 2×105 to find the best velocity profile and smallest pressure drop. Valve installed at a horizontal position with α=0°, 30° CW, and 30° CCW, respectively as the magnitude of valve opening angle and direction. Simulations carried out at three-dimensional, and steady condition. The results give information that fully open valve has small flow resistance only 0.67, pressure drop for valve opens at α=30° CCW smaller than α=30° CW, 3.50 and 3.70 respectively. Velocity profile at the end of downstream does not recover to its recovery profile for each position of valves opening, but valve opens at α=30° CW closer to the recovery profile than valve at α=30° CCW.
