| THE AIM OF THE " FLUID MACHINERY" COURSE IS TO ANALYZE THE ENERGY CONVERSION MECHANISMS IN FLUID MACHINERIES AND ENERGY SYSTEMS AS WELL AS THE RELATED DESCRIPTION OF THEIR OPERATING CONDITIONS KNOWLEDGE AND UNDERSTANDING OPERATING PRINCIPLES OF VARIOUS FLUID MACHINES AND THERMAL ENGINE SYSTEMS. UNDERSTANDING OF THE ENERGY CONVERSION ISSUES AND ENERGY BALANCES. KNOWLEDGE OF ENERGY CONVERSION SYSTEMS AND PLANTS, OF THE CHARACTERISTIC CURVES OF PUMPS AND COMPRESSORS AND OF THEIR INTEGRATION IN PLANTS. APPLIED KNOWLEDGE AND UNDERSTANDING - ENGINEERING ANALYSIS TO ANALYZE THE ENERGY STREAMS IN ENERGY CONVERSION POWER PLANTS AND THE CRITICAL ISSUES RELETALED TO THE ENERGY SAVING. APPLIED KNOWLEDGE AND UNDERSTANDING - ENGINEERING DESIGN TO CARRY OUT THE ROUGH SIZING OF PUMPS COMPRESSORS AS WELL AS OF THERMAL POWER PLANTS. APPLIED KNOWLEDGE AND UNDERSTANDING – INVESTIGATION SKILLS ABILITY IN ORGANIZING AND CARRYING OUT EXPERIMENTAL INVESTIGATIONS ON PUMPS AND COMPRESSORS. ABILITY IN INTERPRETING EXPERIMENTAL DATA AND DRAWING CONCLUSIONS MAKING JUDGMENTS - ENGINEERING PRACTICE ABILITY IN IDENTIFYING THE MOST SUITABLE ENERGY CONVERSION SYSTEMS AND THE TYPE OF FLUID MACHINERIES TO BE INSTALLED IN A PLANT, OPTIMIZING THE ENERGY FLUXES ACCORDING TO THE ANALYZED CONTEXT. COMMUNICATION SKILLS - TRANSVERSAL SKILLS ABILITY IN PRESENTING ORALLY A TOPIC RELATED TO FLUID MACHINERIES AND ENERGY CONVERSION SYSTEMS. ABILITY TO LEARN - TRANSVERSAL SKILLS ABILITY IN APPLYING THE ACQUIRED KNOWLEDGE TO CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE AND IN DEEPENING THE DISCUSSED TOPICS WITH SOURCES DIFFERENT FROM THOSE SUGGESTED. |
| Prerequisites | |
|---|---|
| TO UNDERSTAND AND APPLY THE TOPICS ANALYSED IN THE COURSE, IT IS MANDATORY PASSING THE PROPAEDEUTIC EXAM OF THERMODYNAMICS OF CHEMICAL ENGINEERING. |

| 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 2 HOURS, 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 THERMAL ENGINE SYSTEMS, OPERATING MACHINES, WORK EXCHANGES AND THERMODYNAMICS APPLIED TO THE MACHIES. 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 THERMAL ENGINE 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 THERMAL ENGINE 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. |
