Two concentric cylinders of radii a and b respectively (a > b) have their common axislying along the z-axis. The space between them b < r < a contains fluid of viscosity µ.A flow is generated by moving the outer cylinder with constant speed U parallel to itsaxis whilst the inner cylinder remains at rest.
1. Use cylindrical polar coordinates (r, θ, z) and consider an elementary fluid elementof lengths dr and dz and angle dθ (measured from the z-axis). Draw a diagramshowing the forces acting on the surfaces of the fluid element.
2. Determine the velocity distribution u in thez-direction, stating any assumptions you make.
The velocity field of a flow is described by V-›= (4x) i-›+ (5y + 3) j-›+ (3t2)k-›. What is the pathline of a particle at a location (1 m, 2 m, 4 m) at time t = 1 s?
