Additional file 1 of CRRT circuit venous air chamber design and intra-chamber flow dynamics: a computational fluid dynamics study

Additional file 1. Animations of particles following the streamlines of theflow fields.Animations were created of particles flowing along the streamlinesobtained by numerical analysis. In the horizontal inflow chamber,irrespective of filter presence, the working fluid divided into upwardand downward directions after inflow and ultimately flowed spirallydownstream along the chamber wall. This vortex flow decreased as itflowed downstream. With the filter, the working fluid uniformly flowed outfrom the filter, showing the streamlining effect of the filter. On the otherhand, without the filter, the flow was disturbed in the bottom part of thechamber.In the vertical inflow chamber, irrespective of filter presence, theworking fluid flowed vertically from the inlet into the main direction offlow, then rebounded at the bottom of the chamber, and after ascendingand descending again, flowed out through the outlet. Additionally, atpositions higher than the inlet, streamline plots were not drawn due tostagnation.
