The purpose of this research is to develop a test method to evaluate the characteristics of non-Newtonian fluid by using MPS (Moving Particle Simulation) and equipment. Brookfield type viscometer is widely used as a method to evaluate the characteristics of non-Newtonian fluid. The device can evaluate the viscous properties of fluids well within a certain range. However, due to the measurement principle of the device, it is difficult to evaluate the characteristics of fluid that slip on the surface of the spindle. Therefore, in this study, we investigated a test method that may be able to evaluate the viscous properties of even the above-mentioned fluids. Therefore, we focused on the inclined flow test recently proposed in the civil engineering field. Inclined flow test is applied to evaluate the shape of fluid collapse. Newtonian fluid was used as the reference for the analysis, and pseudoplastic fluid was used as a representative of non-Newtonian fluid. By unifying the flow distance and analyzing the curvature of fluid collapse, it might be possible to evaluate index of power law model.
