Prerequisites
TO UNDERSTAND AND APPLY THE TOPICS ANALYSED IN THE COURSE, IT IS MANDATORY PASSING THE PROPAEDEUTIC EXAM OF THERMODYNAMICS OF CHEMICAL ENGINEERING.
Contents
THE COURSE CONSISTS OF 60 HOURS (6 ECTS) DIVIDED INTO THEORETICAL LESSONS, NUMERICAL EXERCISES AND GUIDED EXERCISES IN LABORATORY. THE MAIN TOPICS ADDRESSED IN THE COURSE ARE:
1) ENERGY SOURCES (5H THEORY)
CLASSIFICATION AND DESCRIPTION OF MACHINES. ENGINE AND OPERATING MACHINES. ENERGY SOURCES. PRIMARY SOURCES AND END USES. FUELS. RENEWABLE ENERGIES. ENERGY, ENVIRONMENT AND ECONOMY INTERACTIONS. NOTES ON THE ITALIAN AND REGIONAL ENERGY SYSTEM.
2) THERMODYNAMICS OF MACHINES (6H THEORY; 3H EXERCISES)
OPEN AND CLOSED SYSTEMS, THERMODYNAMIC PLANS, REVERSIBLE AND IRREVERSIBLE THERMODYNAMIC TRANSFORMATIONS. FIRST AND SECOND THERMODYNAMICS PRINCIPLES. ENERGY EQUATION IN THERMODYNAMIC AND MECHANICAL FORM AND ITS APPLICATIONS. CYCLIC TRANSFORMATIONS, CARNOT CYCLE, EFFICIENCIES. COMPRESSION AND EXPANSION TRANSFORMATIONS.
3) WORK EXCHANGE IN TURBOMACHINERY (5H THEORY; 2H EXERCISES)
EULER EQUATION. SPEED TRIANGLES. REACTION GRADE. AXIAL TURBINE ENGINES. IDEAL STAGE R=0, R=0.5. NOTES ON REAL OPERATION. POWER LIMITS. REGULATION AND CHOCKING.
4) OPERATING MACHINES (12H THEORY; 5H EXERCISES; 2H LABORATORY)
APPLICATION FIELDS, HEAD AND PRESSURE LOSSES. PUMPS AND COMPRESSORS. RADIAL MACHINES, CHARACTERISTIC CURVES, REDUCED PARAMETERS. PUMP REGULATION, CHOCING, SPEED AND BY-PASS. CAVITATION, NPSH. VOLUMETRIC COMPRESSORS, VOLUMETRIC EFFICIENCY AND COMPRESSION RATIO. EXPERIMENTAL CHARACTERISTICS OF AN IDRAULIC OPERATIONAL MACHINE.
5) THERMAL ENERGY SYSTEMS (2H THEORY; 1H EXERCISES)
IDEAL, LIMIT AND REAL CYCLES. GLOBAL EFFICIENCY AND SPECIFIC CONSUMPTION. EFFICIENCIES CHAIN.
6) STEAM POWER PLANTS (6H THEORY; 2H EXERCISES)
APPLICATIONS. RANKINE AND HIRN CYCLES. SUPERHEATING AND REGENERATION. STEAM GENERATORS. PLANT TYPES. REGULATION.
7) GAS POWER PLANTS (6H THEORY; 3H EXERCISES)
APPLICATIONS. JOULE CYCLE. WORK AND EFFICIENCY. INTERCOOLING AND REHEAT. REGENERATION. PLANT TYPES. REGULATION. COMBINED CYCLES.
Teaching Methods
ATTENDING THE COUSE IS HIGHLY RECOMMENDED. TEACHING INCLUDES 42 HOURS OF CLASSROOM THEORETICAL LESSONS IN CLASSROOM, 16 HOURS OF CLASSROOM NUMERICAL EXERCISES AND 2 HOURS OF GUIDED LABORATORY EXERCISES. LABORATORY EXERCISES ADDRESS THE MEASUREMENTS OF CHARACTERISTIC CURVES OF A HYDRAULIC OPERATING MACHINE.
Verification of learning
THE SUCCESSFUL ACHIEVEMENT OF COURSE OBJECTIVES WILL BE ASSESSED THROUGH AN EVALUATION EXAM (30 IS THE MAXIMUM MARK). VERIFICATION INVOLVES A WRITTEN NUMERICAL TEST, BEYOND WHICH THE STUDENT WILL BE ABLE TO TAKE THE ORAL TEST IN A FOLLOWING DATE.
THE WRITTEN NUMERICAL TEST, OF AN AVERAGE DURATION OF 30 MINUTES, CONSISTS IN SOLVING A PROBLEM OF THE SAME TYPE AS THOSE SOLVED DURING THE CLASSROOM EXERCISE HOURS AND AVAILABLE ON THE TEACHING WEBSITE. THE ORAL TEST CONSISTS IN A DISCUSSION FOCUSED ON THE EVALUATION OF THEORETICAL KNOWLEDGE, AUTONOMY OF ANALYSIS AND JUDGEMENT AND COMMUNICATION SKILLS. PARTICULARLY, QUESTIONS ARE FORMULATED WITH RESPECT TO APPLICATIONS AND OPERATING PRINCIPLES OF FLUID MACHINERY AND ENERGY CONVERSION SYSTEMS.
THE FINAL MARK GENERALLY COMES FROM THE AVERAGE OF THE TWO TESTS.
THE EVALUATION OF THE TESTS TAKE INTO ACCOUNT THE CAPABILITIES OF SELECTING THE MOST SUITABLE METHODS FOR THE ANALYSIS OF THE OPERATING MACHINES AND THE ENERGY CONVERSION SYSTEMS, EXPRESSING IN A CLEAR AND CONCISE WAY THE OBJECTIVES, THE METHOD AND THE RESULTS OF THE PROCESSING, AS WELL AS DEEPENING THE TOPICS WITH REFERENCES DIFFERENT FROM THOSE SUGGESTED.
TO ACHIEVE THE MINIMUM EVALUATION LEVEL TO PASS THE EXAMINATION (18/30), IT IS MANDATORY FOR THE STUDENT TO CORRECTLY FORMULATE OF THE ENERGY EQUATION APPLIED TO THE ENGINE AND OPERATION MACHINES, REPRESENT THE COMPRESSION AND EXPANSION TRANSFORMATIONS ON THERMODYNAMIC PLANS, ANALYSE THE ENERGETIC FLUXES AND COMPUTE THE WORK AND EFFICIENCY OF A ENERGY CONVERSION SYSTEM.
THE MAXIMUM EVALUATION LEVEL (30/30) IS GIVEN WHEN THE STUDENT PROVES HIS COMPLETE AND WIDE KNOWLEDGE OF THE OPERATING PRINCIPLES OF THE MACHINES AND HIS COMPETENCE IN USING THE STUDIED METHODOLOGIES AND SOLUTIONS, IN ADDITION TO THE CAPABILITY OF ANALYZING AND SOLVING TECHNO-ENERGETIC PROBLEMS AND SUMMARIZING THE IDENTIFIED SOLUTIONS.
THE MAXIMUM EVALUATION WITH HONORS (30/30 CUM LAUDE) IS GIVEN WHEN THE STUDENT PROVES AN OUTSTANDING COMPETENCE ON THE THEORETICAL AND OPERATIONAL TOPICS AS WELL AS HIGH COMMUNICATION AND INVESTIGATION SKILLS ALSO IN CONTEXT DIFFERENT FROM THOSE PROPOSED BY THE TEACHER.
