Mean Pressure Distributions on the Vanes and Flow Loss in the Branch in a T Pipe Junction with Different Angles

Mean pressure distributions on the vanes and the flow loss in the branch duct in a T pipe junction with different angles are experimental studied. Pressure coefficient drops gradually along the wall but changes suddenly on the four vanes with angle variation. Angle variation has little influence on the mean pressure distribution on the wall. The influence of angle variation on the pressure of the four vanes is described. The maximum average pressure coefficient on the vanes is at theta=130 degrees. (C) 2017 Published by Elsevier Ltd.
