First course of a two-course sequence in fluid mechanics for aerospace engineers. Topics covered include basic governing equations of incompressible fluid flow, potential flow theory, analysis of elementary 2D incompressible flows using superposition of elementary flows, analysis of airfoils using conformal mapping and classical thin airfoil theory, introduction to Helmholtz vortex theorems and Biot-Savart Law, aerodynamics of finite span wings and Prandtl lifting line theory.
