Aerodynamics

5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.

Topics

Airfoil Characteristics
Airfoil characteristics link section shape to lift, moment, and stall behavior, forming the basis of wing design in Anderson-style analysis.
Potential Flow Theory
Potential flow models inviscid irrotational motion and gives closed-form velocity fields used to build intuition before viscous CFD.
$Circulation Γ = ∮ V\cdot dl gives lift via Kutta-Joukowski theorem$
Compressible Flow
Compressible-flow relations connect Mach number to temperature, pressure, and area changes in nozzles and high-speed ducts.
Boundary Layer and Drag
Boundary-layer growth controls skin friction, separation onset, and ultimately the drag breakdown of an aerodynamic body.
Lift and Drag Estimation
Lift-drag estimation converts non-dimensional coefficients into actual forces and supports sizing for cruise, climb, and glide.
$Induced drag c_{di} = \frac{c_{l}^{2}}{(\pi e AR)}$
