Abstract
Chronis kidney disease is one of the health problem in Indonesia. The common therapy is using hemodialyzer machine. The effectiveness of the dialyzer depend on the mass transfer through the membrane. This paper in aimed to simulate the fluid flow of biofluid through the microchannel permable membrane with dimension of 4 mm x 10 mm, with thickness of 10 micrometer, and pore size of 3 micrometer. The result show that the bigger the mass transfer occurs through the permeable membrane. The fluid flow of 10, 20, 30 and 40 ml/minute causes the diffusion rate of 6.5, 8.9, 18.34 and 28 ml/minute each. The shear stress in the corrrsponding fluid flow are 42.75, 39.99, 34.57 and 31.21 Pa. While the transmembrane pressure resulted by the cporresponding fluid flow are 1050.74, 1125.28, 1704.68 and 2633.68 Pa, each.
