Flow potential eccentricity
WebFlow potential eccentricity, . The eccentricity is a small positive number that defines the rate at which the hyperbolic flow potential approaches its asymptote. The default is ., the ratio of initial equibiaxial compressive yield stress to initial uniaxial compressive yield stress. WebThe combined effects of flow resistance and stratified flow lead to the above variation pattern of cement displacement interface. When the casing is in the middle or the eccentricity is small, the flow resistance between the gaps in the annulus does not show much difference, and the stratified flow of two-phase fluid plays a major role.
