  • The rotational dispersion coefficient of the fiber in the turbulent shear flow of fiber suspension was studied theoretically.The function of correlation moment between the different fluctuating velocity gradient of the flow was built.Then the expression of rotational dispersion coefficient is derived.Which is dependent on the characteristic length,time,velocity and a dimensionless parameter related to the effect of wall.The derived expression of rotational dispersion coefficient can be employed to the inhomogeneous and non-isotropic turbulent flows.Furthermore it can be expanded to three-dimensional turbulent flows and serves as the theoretical basis for solving the turbulent flow of fiber suspension.
