JNTUK B.Tech IC Engines & Gas Turbines gives you detail information of IC Engines & Gas Turbines R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective: The aim is to introduce the concepts of I.C.Engines, compressors, Gas turbines and the steam turbines, which are used in the field of aeronautical engineering. The geometrical and operational details of the aforementioned systems along with the necessary auxiliary components shall be dealt in detail.
UNIT – I : Objectives: To familiarize the student with the operational principles of various types of engines and their systems along with applications. Further, the student shall distinguish between the phenomenon of normal and abnormal combustion of spark ignited engines along with the factors affecting the combustion.
I. C. ENGINES : Classification – Working principles, Valve and Port Timing Diagrams, – Engine systems – Fuel, Carburetor, Fuel Injection System, Ignition, Cooling and Lubrication, principle of wankle engine, principles of supercharging and turbocharging.
Combustion in S.I. Engines: Normal Combustion and abnormal combustion – Importance of flame speed and effect of engine variables – Type of Abnormal combustion, pre-ignition and knocking. Fuel requirements and fuel rating, anti knock additives – combustion chamber – requirements, types.
UNIT – II : Objectives: To make the student learn to perform testing on S.I and C.I Engines for the calculations of performance and emission parameters. Measurement, Testing and Performance: Parameters of performance – measurement of cylinder pressure, fuel consumption, air intake, exhaust gas composition, Brake power – Determination of frictional losses and indicated power – Performance test – Heat balance sheet and chart.
UNIT – III : Objectives: To impart the knowledge of gas turbine fundamentals, the governing cycles and the efficiency improvement techniques.
GAS TURBINES: Simple gas turbine plant – open and closed cycle arrangements – ideal cycle and their analysis – essential components – parameters of performance – actual cycles and their analysis – regeneration, inter cooling and reheating – merits and demerits.
UNIT – IV : Objectives: To make the student learn about the geometrical and operational details of the compressors that are used in aeronautical field.
COMPRESSORS: Centrifugal compressors: Essential parts-principle of operation, flow analysis-performance parameters- losses and characteristics.
Axial compressors: Essential parts-principle of operation, flow analysis-performance parameters- losses and characteristics – comparison between axial and centrifugal compressors.
UNIT – V : Objectives: The make the student understand the fundamentals of combustion theory and types of combustion chambers of gas turbines.
COMBUSTION SYSTEM: Combustion theory – combustion chamber requirements – factors affecting combustion chamber design & performance –– combustion chamber geometry & types.
UNIT – VI : Objectives: The student shall understand the operation and construction of types of steam turbines. He shall be able to calculate the performance of the turbines with the help of velocity triangles.
IMPULSE AND REACTION TURBINES: Velocity triangles – expression for work output and efficiency – compounding of multistage impulse turbines – performance – losses.
