Abstract: In this paper,B.B. Golubef method is first extended to analyze the laminarboundary layer development flow of power-law fluid between two parallel disks.With theboundary layer motion equation,we have derived both the momentum integral equationand the energy integral equation. Then by solving the momentum integral equation,thedevelopment of the boundary layer in the entrance region and coefficients of the entranceregion effect are analyzed and calculated. Furthermore, the effects of flow-index of power-law fi...
