WebMay 1, 2024 · In this case the Navier-Stokes equation is written in cylindrical coordinates as shown in Table 7.1 and then reduced for steady, constant area, incompressible, constant property flow. Again, the flow has no acceleration for steady, constant area flow and the result is a balance of pressure and viscous forces in the $z$, or axial direction. WebThe major practical effects of viscous flow on aerodynamic problems are the following: 1. The action of viscosity generates a shear stress at a solid surface, which in turn creates a …
