AIM:
 To impart knowledge to the students on compressible flow through ducts, jet
propulsion and space propulsion.
OBJECTIVE:
 To understand the basic difference between incompressible and compressible
flow.
 To understand the phenomenon of shock waves and its effect on flow. To gain
some basic knowledge about jet propulsion and Rocket Propulsion.
UNIT I BASIC CONCEPTS AND ISENTROPIC FLOWS 6
Energy and momentum equations of compressible fluid flows – Stagnation states, Mach
waves and Mach cone – Effect of Mach number on compressibility – Isentropic flow
through variable ducts – Nozzle and Diffusers – Use of Gas tables.
UNIT II FLOW THROUGH DUCTS 9
Flows through constant area ducts with heat transfer (Rayleigh flow) and Friction (Fanno
flow) – variation of flow properties – Use of tables and charts – Generalised gas
dynamics.
UNIT III NORMAL AND OBLIQUE SHOCKS 10
Governing equations – Variation of flow parameters across the normal and oblique
shocks – Prandtl – Meyer relations – Use of table and charts – Applications.
UNIT IV JET PROPULSION 10
Theory of jet propulsion – Thrust equation – Thrust power and propulsive efficiency –
Operation principle, cycle analysis and use of stagnation state performance of ram jet,
turbojet, turbofan and turbo prop engines.
UNIT V SPACE PROPULSION 10
Types of rocket engines – Propellants-feeding systems – Ignition and combustion –
Theory of rocket propulsion – Performance study – Staging – Terminal and characteristic
velocity – Applications – space flights.
