%X By means of numerically simulating mass transfer of urea at four different placements (placed horizontally with dialysate entrance up, placed horizontally with dialysate entrance down, placed vertically with blood flow direction up, placed vertically with blood flow direction down) of artificial kidney, we qualitatively investigate the effect of gravity on mass transfer performance of hemodialysis, and acquire 3-D concentration fields and clearances of urea at all placements. The results indicate that the effect of gravity on mass transfer of artificial kidney is notable. Under the gravity effect, the clearance with blood flow direction up (module is placed vertically) is the greatest, and the clearance with dialysate entrance up (module is placed horizontally) is the second. The results are of significance in improving the clinical efficiency and optimizing design of artificial kidney.
