An investigation of multiphase flow in complex microchannel geometries for hemodialysis systems using residence time distribution analysis

Creator:: Coblyn, Matthew Y.
Abstract:: There are approximately 2.2 million cases of End-stage Renal Disease (ESRD) worldwide and current hemodialysis treatment is costly and ultimately insufficient compared to kidney transplantation. There is a strong need to arrive at a better solution for treating ESRD. Microchannel-based hemodialysis is one proposed option, already shown to have improved...
