N2 - A fundamental study is made on a method of numerical measurement of the effective viscosity of Solid-Liquid mixture, in which gravimetric type capillary viscometer is employed for the measurement procedure. The Hagen-Poiseuille equation is applied to evaluate the effective viscosity with the data obtained from a series of numerical test in a control volume and the Space-Time averaging procedure. The behaviour of sediments in the control volume is represented as spherical rigid bodies and is analysed with the Distinct Element Method (DEM), the interaction between liquid and sediments is considered with the help of the Finite Cover Method (FCM). Several numerical examples are presented to examine the viscosity dependence on the volume fraction and particle motions.
