Effect of Concentric Annular Gap Flow on Wall Shear Stress of Stationary Cylinder Pipe Vehicle under Different Reynolds Numbers

Figure 17

The distribution of wall shear stress and velocity along the length of the cylinder pipe vehicle. (a) The distribution of wall axial average shear stress. (b) The distribution of wall circumferential average shear stress. (c) The distribution of axial average velocity. (d) The distribution of circumferential average velocity. Note: the ordinate is the absolute value of the wall circumferential shear stress and flow velocity in (b) and (d).
