Abstract
In an effort to assess the effect of dialysate flow rate on solute removal in a hemodialyzer and to analyze solute transfer using di sion s numbers, an overall imensionless equation -Sh=0.67(Gz)1/3(Re)0.73- has been developed for six commercially available dialyzers for urea and creatinine. Some of the dialyzers require design modification because the improved flow pattern in the dilaysate space results in an increased clearance. In other cases, the flow pattern was not particularly satisfactory despite the fact that clearance was high.
