Exit jet and recirculating flow pattern of pump

Video Author: Richard Malinauskas PhD
Published on: 03.27.2017
Associated with: ASAIO Journal. 63(2):150-160, March/April 2017

At test condition 5, the outlet jet in the exit diffuser was skewed toward the outer wall in all four data sets. This asymmetry created a large recirculation region near the inner wall of the pump diffuser. Video demonstrates the exit jet and recirculating flow pattern.

Top view topography map of Valve 1 vs. Valve 2
Creator: Pablo S Huang Zhang
Duration: 0:17
Top view of the intensity topography maps (i-Maps) depicting washout patterns of Valve 1 and Valve 2. The brighter color denotes higher DBCS concentrations, while the darker blue denotes lower or absence of DBCS. Note: The bright “sun-spot” that remains in the intensity plots after washout is a reflection artifact resulting from the microscope illumination.
