SOLVED:The beautiful expression for lift of a two-dimensional airfoil, Eq. (8.69), arose from applying the Joukowski transformation, ζ=z a^2 / z, where z=x i y and ζ=η i βThe constant a is a length scale. The theory transforms a certain circle in the z plane into an airfoil in the ζplane. Taking a=1 unit for convenience, show that (a) a circle with center at the origin and radius >1 will become an ellipse in the ζplane and (b) a circle with center at x= -ϵ<1, y=0, and radius (1 ϵ) will become an

A high-performance race car with an adjustable wing (airfoil) is shown in Figure P1.20. Develop a block diagram describing the ability of the airfoil to keep a constant road adhesion between the car's tires and the race track surface. Why is it important to maintain good road adhesion?

Calculate the drag on a symmetric airfoil shown in Fig. 2.14 assuming the angle of attack to be zero and using the control volume specified in the figure. The velocity upstream of the airfoil is U= constant. The variation of the velocity downstream of the airfoil, u(y), is defined as u(y)=u1(|y|), where u1(y) is a cubic polynomial function that satisfies the following conditions: 1. u1(0)=U / 2 2. d u1 / d y(0)=0 3. u1(b / 2)=U 4. d u1 / d y(b / 2)=0 One assumes the flow is steady and incompress
