  7. Abstract:
  8. Due to largre number of patients treated by dialysis and its significant increasing progress, dialysis efficiency and patients' life quality are of great interest.Dialyzer, the dialysis beating heart, has the role of cleaning blood by removing toxic solutes and balancing volume of bood's water through hollow fiber membranes. In this thesis, firstly we tried to focus on performance characteristics of dialyzer by studying effective parameters influencing dialyzer efficiency and ultimately we set two important performance characteristics, ultrafiltration coefficient and solute clearance, as our goal parameters for evaluating dialyzer's yield. To this purpose, we designed an experimental set up to determine these two factors for four different types of dialyzers. These dialyzers were chosen on the basis of same surface area. We also study the effect of different operational conditions like blood flow rate, dialysate flow rate and ultrafilrtration rate on dialyzer efficiency. In order to make our tests' condition more like reality, we designed a different set up in which blood can circulate between dialyzer and its containing tank.In this section, the best results obtained among our four different dialyzers was by PES130 dialyzer and this dialyzer showed the best performance characteristics.In the second part of thesis, by considering a meaningful geometery, deriving right governing equations and determining suitable boundry conditions, we developed a model to predict dialyzer efficiency and validate our model with the experimental results. By comparing the results gained by the model and experimental results, there was a good agreement between these two data
