Freeze and cherry effective porosity

WebEffective porosity is defined as the effective pore volume of the pores to the volume of the wheel on the wheel surface as shown in Fig. 10.11. The effective porosity is different from the overall porosity within the wheel structure defined by Eq. (10.1). The effective porosity ratio describes the openness of the wheel at the surface.
