JNTUK B.Tech Gas Dynamics and Jet Propulsion gives you detail information of Gas Dynamics and Jet Propulsion R13 syllabus It will be help full to understand you complete curriculum of the year.
Course objectives
The purpose of this course is to provide the student with the knowledge of basic principles of gas dynamics and its importance in jet propulsion applications.
UNIT-I : Introduction to gas dynamics: control volume and system approaches acoustic waves and sonic velocity – mach number – classification of fluid flow based on mach number – mach cone-compressibility factor – general features of one dimensional flow of a compressible fluid – continuity and momentum equations for a control volume.
UNIT-II : Isentropic flow of an ideal gas: basic equation – stagnation enthalpy, temperature, pressure and density-stagnation, acoustic speed – critical speed of sound- dimensionless velocity-governing equations for isentropic flow of a perfect gas – critical flow area – stream thrust and impulse function. Steady one dimensional isentropic flow with area change-effect of area change on flow parameters- chocking- convergent nozzle – performance of a nozzle under decreasing back pressure -De lavel nozzle – optimum area ratio effect of back pressure – nozzle discharge coefficients – nozzle efficiencies.
UNIT- III : Simple frictional flow: adiabatic flow with friction in a constant area duct- governing equations – fanno line limiting conditions – effect of wall friction on flow properties in an Isothermal flow with friction in a constant area duct- governing equations – limiting conditions. Steady one dimensional flow with heat transfer in constant area ducts- governing equations Rayleigh line entropy change caused by heat transfer – conditions of maximum enthalpy and entropy.
UNIT-IV : Effect of heat transfer on flow parameters: Intersection of Fanno and Rayleigh lines. Shock waves in perfect gas- properties of flow across a normal shock – governing equations – Rankine Hugoniat equations – Prandtl’s velocity relationship – converging diverging nozzle flow with shock thickness – shock strength.
UNIT- V : Propulsion: Air craft propulsion: – types of jet engines – energy flow through jet engines, thrust, thrust power and propulsive efficiency turbojet components-diffuser, compressor, combustion chamber, turbines, exhaust systems.
UNIT-VI : Performance of turbo propeller engines, ramjet and pulsejet, scramjet engines. Rocket propulsion – rocket engines, Basic theory of equations – thrust equation – effective jet velocity – specific impulse – rocket engine performance – solid and liquid propellant rockets – comparison of various propulsion systems.
