The purpose of the study involves conducting numerical simulations that elucidate the laminar flow dynamics within a horizontal pipe. The investigated flowing medium consists of bentonite suspensions with varying concentrations. The rheological behavior of the fluid is accurately described using the Herschel-Bulkley model, a pseudo-plastic representation. The results obtained through this research have helped to meticulously analyze the influence of fluctuations in the rheological index n on the following flow key parameters: pressure drop, velocity, and coefficient of friction within the pipe. This analysis covers a range of generalized Reynolds numbers, all the values of which correspond to the laminar flow regime. The meticulous study of the flow parameters reveals a compelling alignment between the simulation results and the experimental measurements, which underscores the validity of the study's findings. https://jcamech.ut.ac.ir/article_96340_9aab0d0c693fe9f2ec6ea39025573e46.pdf
