Question

The stated boundary condition associated with Equation (8.69) is that $V_r(0)=0$. This is a symmetry condition consistent with the assumption that $V_\theta=0$. There is also a zero-slip condition that $V_r(R)=0$. Prove that both boundary conditions are satisfied by Equation (8.70). Are there boundary conditions on $V_z$ ? If so, what are they?

Step 1

The first boundary condition is \( V_r(0) = 0 \), which indicates that at the center (radius \( r = 0 \)), the radial velocity is zero. The second boundary condition is \( V_r(R) = 0 \), which indicates that at the boundary (radius \( r = R \)), the radial Show more…
