FN R A two-dimensional analysis on the flight of FL an airfoil is shown in the figure. The airfoil shape is traveling at a certain velocity and meets the incoming airflow at an angle of attack a. As shown, the forces affecting FD the flight of the airfoil is the drag force a FA (FD), lift force (F) and the two other Vo variable forces (Fn and Fa) acting normal and axial on the airfoil. The lift force (Fi) on the airfoil is a function of its length L, velocity V, diameter D, angle of attack a, density p, viscosity u, and speed of sound c of the air (i.e. FL = f(L, V, D, a, P, µ, c). Use dimensional analysis to show that the lift coefficient Cis a function of a set of dimensionless parameters. Also, is air temperature T, a significant variable in the function of the lift force? Use p,V,D and Ta as repeating variables.
b) Uniform streams of fluid cross the boundary of a control volume containing a solid object. Briefly explain how Newton's 2nd and 3rd laws allow the resultant force vector acting on the body to be derived. Figure 2 shows a steady, uniform two-dimensional jet of liquid in the atmosphere impinging on a flat plate inclined at an angle q to the jet axis. The jet cross section area is A, and its velocity is u. The liquid density isr. It is assumed that there are no flow losses, and that all the streamlines end up parallel to the plate. Explain why the resultant force acts perpendicular to the plate, and show that its magnitude is: R22. A.u cosa Figure 2 A
