Witryna27 lip 2010 · (1) For steady and fully developed flow of an incompressible fluid, it becomes: (2) Therefore, rv = constant. Since the radial velocity at the wall is zero (impermeability condition), it can be concluded that v = 0 everywhere in the flow field. The steady parabolic momentum equation in the x -direction can be written in … Witryna15 kwi 2024 · The previous work has reported that higher corrosion resistance of a material or surface treatment under the static condition does not always correspond to higher erosion–corrosion resistance, ... The results in this case are associated with the good impermeability and hydrophobicity of the stearic acid–sealed layer [14,15,16].
