AERONAUTICAL ENGINEERING


AERO  ENGINEERING THERMODYNAMICS


UNIT-I      BASIC CONCEPTS AND FIRST LAW                                        

Concept of continuum, macroscopic approach, thermodynamic systems – closed, open and isolated. Property, state, path and process, quasi-static process, work, modes of work, Zeroth law of thermodynamics- concept of temperature and heat, internal energy, specific heat capacities, enthalpy - concept of ideal and real gases. First law of thermodynamics - applications to closed and open systems - steady flow processes with reference to various thermal equipment’s.

UNIT-II        SECOND LAW AND ENTROPY                                                  

Second law of thermodynamics – kelvin Planck and Clausius statements of second law. Reversibility and irreversibility - Carnot theorem. Carnot cycle, reversed Carnot cycle, efficiency, COP - thermodynamic temperature scale - Clausius inequality, concept of entropy, entropy of ideal gas, principle of increase of entropy.


UNIT III     AIR STANDARD CYCLES 



Otto, Diesel, Dual combustion and Brayton combustion cycles – Air standard efficiency - Mean effective pressure – Actual and theoretical PV, TS diagrams of two stroke and four stroke IC Engines.

 

UNIT IV REFRIGERATION AND AIR CONDITIONING                  

           

Principles of refrigeration, Air conditioning - Heat pumps - Vapour compression - Vapour absorption types - Coefficient of performance, Properties of refrigerants.


UNIT V AIR COMPRESSORS            

                                                         

Classification and working principle of compressors (Descriptive Treatment). Isothermal and Isentropic efficiency of air compressors.
