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.

Transapical guidewire and transcatheter heart valve
Creator: Andreas Schaefer
Duration: 0:06
A transapical guidewire was inserted in the middle of the sewing ring, and the crimped 27 mm JenaValve (JenaValve Technology, GmbH, Munich, Germany) transcatheter heart valve (THV) was introduced and deployed into the AV annulus without prior balloon valvuloplasty.

Duration: 0:05
Unsteady heparin concentration vs. time on a 2D plane through the center of a central venous catheter. The concentration is computed using a 3D computational fluid dynamics model. The simulated time of the movie is 1 second. Recall that 1 kg/m3 of heparin is about 500 U/mL
