Research about the internal flow have been done and continues to grow up. One of all is the flow through a rectangular elbow. On the flow characteristic that the rectangular elbow through is so complicated and have many kinds of phenomena. There is the formation of secondary flow. This flow phenomenon occurs because of boundary layer interaction on the corner wall. The effect caused by this secondary flow is the flow blockage (blockage effect), so that reducing the effective flow area. The test model used was Air Flow Bend AF 15 inside Mechanical Engineering Laboratory Termofluid UNDIP with hydraulic diameter (Dh) = 66.7 mm, using the velocity U ≈ 33 m / s and Reynolds Number of 150,000. The variable measured is static pressure using a manometer Multitube Inclinable and connected to wall pressure tappings then can produce wall distribution graph Pressure Coefficient (Cp). Research conducted in experimental and numerical visualization using the software FLUENT GAMBIT 6.3.26 and 2.4.6 in order to provide information about flow phenomena that crosses the rectangular elbow. By using the two methods showed the results of pressure distribution on the outer, inner wall and the radial section and know the amount of discharge (Q) in the inlet, the bend θ = 45 ⁰ and outlet.
