To evaluate material properties of highly viscous fluid is important subject in various kind of industries. Highly viscous fluid sometimes shows much complicated behaviors, and it makes difficult to evaluate properties such as viscosity. Some of them has rheological properties, and the behavior is affected not only by shear deformations but also by compressive or tensile deformations. The purpose of this research is to evaluate rheological properties of highly viscous fluid by separating stress components. In previous works, it was found that components of viscosity coefficients were evaluated independently. However, it was difficult to ignore effects of experimental device edge. In this research, advanced device and system were proposed. To exclude effects of the edge, experimental device design was converted from rectangular to cylindrical type. Therefore, analyzation procedures were also converted in a same manner. It was found that components of viscosity coefficients were evaluated more accurately.
