Mean velocity field relative to a Rushton turbine blade

摘要: The 3-D flow field relative to a rotating Rushton turbine blade is acquired for fully turbulent tank conditions by synchronizing LDA measurements with the output of shaft-mounted encoder. This makes it possible capture impeller stream velocity field, including details voritices behind blades. Mean data at three speeds show extent periodicity and axes structure vortices. Pumping capacities are determined shown that radial jet consequence fluid entrainment into Deformation rates based on gradients mean calculated. Close they can exceed rotational frequency as much two orders magnitude. To first approximation, normalized independent speed.
