2.25 Final Exam Fall 2009 1. Boundary Layer on a Free Surface A two-dimensional liquid fluid stream with height d, uniform velocity U!, density ρ and dynamic viscosity µ is incident on the top side of a flat plate as shown in the Figure. The gravitational acceleration is g and the atmospheric pressure is assumed equal to p a

A free or potential vortex is a flow with circular paths around a central point such that the velocity distribution still satisfies the irrotational condition (i.e. the fluid particles do not themselves rotate but instead simply move on a circular path). See figure 2. Figure 2: Potential vortex with flow in circular patterns around the center.

to the free-stream flow, the velocity is still only 50% of the free-stream value. 10 At every point on the surface of the sphere there is a definite value of fluid pressure (normal force per unit area) and of viscous shear stress (tangential force per unit area). These values also come from Stokes’ solution for creeping flow around a sphere.
