Consider a circular cylinder of radius a whose central axis is stationary. The cylinder is surrounded by a fluid that is moving with a uniform steady velocity Uk far from the cylinder; the cylinder axis is in the z-direction The cylinder is also spinning on its axis with constant angular velocity, Ω2, where x, у and z are the usual Cartesian unit vectors We wish to model this 2D flow using an inviscid approximation. This is achieved by first calculating...

Consider two concentric, infinitely long cylinders. The cylinders are oriented such that the center-line is along the z-axis, and the radii exist in the r-direction. The inner cylinder has a radius of ra and the outer cylinder has a radius Tb. The inner cylinder rotates with an angular velocity of w whereas the outer cylinder is stationary. There is no pressure gradient applied nor gravity. The fluid contained between the cylinders is assumed to be Netwonian, incompressible, isotropic and isothermal....

5. A return to the circular disc problem examined in class (Lecture 2): (Despite all of the text below you are required to do very little. Please read on.) A thin, circular plate assumed to lie on the ry-plane is rotating about its center O, located at (0, 0), with constant angular speed w. (w > 0 means that the plate is rotating in the counterclockwise direction.) Using the results obtained in class, show that the velocity field of of...
