  • Publication number: 20100274504
    Abstract: There is provided a fluid analysis method and its device which are capable of easily analyzing a normal stress difference of a low-viscosity fluid in addition to that of a high-viscosity fluid. A shearing fluidity is applied to a non-Newtonian fluid within a lateral-side gap by pushing a cylindrical bob into a container. At that time, reactive force applied to the cylindrical bob is measured. Then, by practicing an arithmetic process in a given form using the reactive force and each of conditions input by a user, the normal stress difference of the low-viscosity non-Newtonian fluid which is hard to form in a solid state can be certainly determined. Thus, with respect to the low-viscosity non-Newtonian fluid in addition to the high-viscosity non-Newtonian fluid, the normal stress difference can be easily analyzed.
