摘要：This study presents a theoretical and experimental analysis of laminar flow behavior of high-viscous non-Newtonian power-law and Bingham fluids in multiple structural bifurcation channel distributors. Theoretical models are derived to describe velocity profiles, shear rate distribution, and pressure drop across specific channels. Modified pressure drop models are proposed based on experiments on 6 kinds of non-Newtonian fluids and 3 types of bifurcation channel distributors with different transition areas. Specifically, the deviations between the theoretical models and the experimental results are systematically analyzed, and models were modified with correction coefficients based on Reynolds number and dimensionless shape factor. The theoretical results, modified results and experimental data are compared and discussed to ensure the accuracy of the modified models, demonstrating a significant improvement in the prediction of pressure drops for high-viscous non-Newtonian fluids in certain types of bifurcation channels. Additional experiments and analyses were carried out to validate the modified models and the results suggest that the models offer a certain degree of universal applicability in bifurcation channel designs. It implies that for other types of bifurcation channel distributors, similar correction methods based on Reynolds number and shape factor may also be applicable even with different coefficients.
