This paper derives the expression of dynamic friction coefficient for collisional granular flows at flat walls.An important character of the new expression is that the effect of inhomogeneous of flows on the friction is under the consideration by using the velocity distribution function of particles described by the second-order solution of the Boltzmann equation rather than the Maxwellian velocity distribution.
