and moment coefficients and be able to estimate their magnitudes.
· Equations of fluid motion
1. Explain the continuity and momentum conservation laws in 3-D. 2.
Explain the relationship between the Navier-Stokes, Euler and Bernoulli
equations. 3. Explain the substantial derivative.
· Flow fundamentals 1.
Calculate streamlines, vorticity and circulation from given velocity fields
and visa versa. 2. Correctly apply Bernoulli's equation. 3.
Compute the stream and potential functions for uniform, source/sink,
doublet and point vortex flows. 4. Explain the vortex theory of lift
(Kutta-Joukowski theorem).
· Application to airfoils 1.
Concept of superimposing elementary solutions. 2. Calculate
non-lifting flows over arbitrary 2-D body. 3. Explain the Kutta condition
and calculation of lift. 4. Design a lifting airfoil. 5.
Calculate lift and moment on thin airfoil. 6. Explain thin airfoil
theroy (Prandtl's Theorem).
· Application to finite wings 1.
Explain vortex system that replaces a wing on lifting-line theory
(Helmholtz laws). 2. Explain downwash (Biot-Savart law) and induced
drag. 3. Calculate the aerodynamics of rectangular and
elliptical-planform wings. 4. Explain vortex-lattice method for
general wings.
