An Experimental Study of Three Dimensional Flow Structures for Effect of Crossflow on Central Discharge of Wastewater
Abstract:
Effects of crossflow on flow field structures of central discharge were experimentally investigated in the flume. For the sake of comparing and analyzing, longitudinal velocity u, vertical velocity w and transverse velocity v in the near field of central discharge were measured by Micro ADV in stagnant and crossflow waters, respectively. Velocity vectors and velocity profiles on the planes of xoy, yoz and xoz were given. Effects of crossflow on three-dimensional flow structures of central discharge jet were analyzed. The experimental results showed that a phenomena of flow around object occurred when crossflow encountered central discharge jet, which bended jet trajectory downward. The maximum velocity of jet deviated the original location, the deviation depends on initial velocity at the discharge outlet and crossflow velocity.
