| dc.description.abstract | Flow patterns in a multiple disk centrifugal pump for use as an artificial ventricle were analyzed for steady flow. The pump consists of 5 flat, washer-shaped, polycarbonate disks contained within a spiral housing. The disks have a 1.5 inch inner diameter and 3.0 inch outer diameter. Four stainless steel pins affix the disks at a constant spacing of .025 inches and terminate in a sixth solid disk. This solid disk couples the pins to a DC motor shaft which rotates the entire disk assembly. A mock circulatory system based on the NIH/Penn State model was employed with a blood analog of 40% glycerin/60% water. Polystyrene particles (250 microns diameter) were used as neutrally buoyant flow markers. Inlet and outlet' pressures, outlet flow rate, and disk rotation rate were all monitored. A 15mW red HeNe laser provided illumination for the particles. Areas of particular interest include between the disks, the inner cavity, and around the disk periphery. Two "high risk" areas were identified which exhibited potential for thrombus formation. Particle track lengths will be calculated to determine fluid velocities. The overall goal of this study was to develop a better understanding of the flow patterns in the disk pump and identify any regions of flow stagnation. | en |
