OBJECTIVES:
• To introduce the concepts of mass, momentum and energy conservation relating to aerodynamics.
• To make the student understand the concept of vorticity, irrotationality, theory of airfoils and wing sections.
• To introduce the basics of viscous flow.

UNIT I

INTRODUCTION TO LOW SPEED FLOW

Euler equation, incompressible bernoulli’s equation. circulation and vorticity, green’s lemma and stoke’s theorem, barotropic flow, kelvin’s theorem, streamline, stream function, irrotational flow, potential function, equipontential lines, elementary flows and their combinations.

UNIT II

TWO DIMENSIONAL INVISCID INCOMPRESSIBLE FLOW

9

Ideal Flow over a circular cylinder, D’Alembert’s paradox, magnus effect, Kutta joukowski’s theorem, starting vortex, kutta condition, real flow over smooth and rough cylinder.

UNIT III

AIRFOIL THEORY

9

Cauchy-riemann relations, complex potential, methodology of conformal transformation, kutta- joukowski transformation and its applications, thin airfoil theory and its applications.

UNIT IV

SUBSONIC WING THEORY

9
