3. Velocity profiles are measured at the upstream end (surface I) and at the downstream end (surface 2) of the control volume shown in figure below. Surfaces 3 and 4 are streamlines. If the flow is incompressible, two dimensional, and steady, what is the drag coefficient for the airfoil? The vertical dimension Hp = 0.025c. The pressure is Pao (a constant) over the entire surface of the control volume. Streamline (--v-(1-05000 )
Velocity profiles are measured at the upstream end and at the downstream of a 2D channel as shown in the Figure. The horizontal lines indicate the upper and lower walls. The velocity profile at the inlet is U=Uo while at the outlet the velocity has the distribution shown in the figure (2 linear regions near the two walls and a region where the velocity is constant in the center). =U. The pressure at the inlet is P.-P+pU? If the flow...
