3104
AIM:
„h To impart knowledge to the students on compressible flow through ducts, jet
propulsion and space propulsion.
OBJECTIVE:
„h To understand the basic difference between incompressible and compressible
flow.
„h 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.
