IN THE FIRST HALF THE STUDY OF APPLIED THERMODYNAMICS IS FACED, IN THE SECOND HALF THE STUDY OF HEAT TRANSFER. KNOWLEDGE AND UNDERSTANDING THE MAIN KNOWLEDGE ACQUIRED BY THE STUDENT IN THE COURSE ARE: - I AND II LAW OF THERMODYNAMICS FOR CLOSED AND OPEN SYSTEMS - MODELS OF STATE THERMODYNAMICS - APPLICATIONS OF I AND II THERMODYNAMICS LAW ON COMPONENTS OF HEATING SYSTEMS - PROPERTIES AND TRANSFORMATIONS OF THE MOIST AIR - STEAM POWER PLANT - HEAT PUMP AND REFRIGERATION SYSTEM - CONDUCTION HEAT TRANSFER - CONVECTION HEAT TRANSFER - RADIATIVE HEAT TRANSFER - FINNED SYSTEMS ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING AT THE END OF THE COURSE THE STUDENT WILL BE ABLE TO: - CALCULATE THE THERMODYNAMIC PROPERTIES - ANALYZE THE COMPONENTS OF A HEATING SYSTEM IN TERMS OF I AND II LAW - ANALYZE A THERMAL POWER PLANT IN TERMS OF I AND II LAW - ANALYZE IN TERMS OF I AND II LAW HEAT PUMPS / REFRIGERATION SYSTEMS - TRANSLATE HEAT TRANSFER PROBLEMS INTO FORMAL LANGUAGE - ADDRESS THE CORRESPONDING ANALYTICAL SOLUTION, EVEN APPROXIMATELY OR GRAPHICALLY AUTONOMY OF JUDGMENT KNOWING HOW TO SELECT THE MOST APPROPRIATE METHODOLOGIES TO ADDRESS THE STUDY INVOLVING ENERGY TRANSFORMATIONS AND TO HEAT TRANSFER COMMUNICATION SKILLS THE STUDENT IS REQUIRED TO BE ABLE TO REPRESENT, BY WRITTEN AND ORAL TESTS, THE CONCEPTS ACQUIRED DURING THE COURSE IN A CLEAR AND COINCISE WAY AND WITH AN APPROPRIATE TECHNICAL LANGUAGE. LEARNING SKILLS THE STUDENT IS REQUIRED TO USE AND APPLY IN SEVERAL CONTEXTS THE HABITS ACQUIRED SO TO DEEPEN TECHNICAL PROBLEMS |
| Prerequisites | |
|---|---|
| FOR THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES, THE KNOWLEDGE OF THE BASIC NOTIONS AS GIVEN IN THE FIRST YEAR COURSES OF MATHEMATICS AND PHYSICS, IS REQUIRED. |

| Teaching Methods | |
|---|---|
| THE COURSE IS DIVIDED IN TWO MODULES (EACH OF 6 CFU) AND INCLUDES 120 HOURS OF ASSISTED DIDACTICS, ARRANGED IN 80 HOURS OF FRONTAL THEORETICAL LESSONS AND 40 HOURS OF CLASSROOM EXERCISES. NUMERICAL EXERCISES SUITABLY SELECTED ARE ASSIGNED TO STUDENTS WITH THE PURPOSE OF DEEPENING THE CONCEPTS CONCERNING THERMODYNAMICS AND HEAT TRANSFER. DURING THE EXERCISES THE TEACHERS ASSIST THE STUDENTS WITH THE PURPOSE OF DEVELOPING AND STRENGTHENING THE STUDENT'S ABILITY IN ADDRESSING THE APPLICATION WHILE RECALLING THE SUBTENDED THEORETICAL CONCEPTS. |
| Verification of learning | |
|---|---|
| THE LEVEL OF ACHIEVEMENT OF TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN EXAM WITH ASSESSMENT IN 30TH. STUDENTS MUST FIRST TAKE THE EXAM (WRITTEN AND ORAL) RELATING TO THE PART OF APPLIED THERMODYNAMICS OF THE COURSE, WHICH IS HELD IN THE FIRST SEMESTER, AND SUBSEQUENTLY THE EXAM (WRITTEN AND ORAL) RELATING TO THE HEAT TRANSFER PART OF THE COURSE, WHICH IS HELD IN THE SECOND SEMESTER. AT THE END OF THE FIRST SEMESTER, THE STUDENT HAS THE POSSIBILITY OF TAKING THE EXAM OF THE APPLIED THERMODYNAMICS PART IMMEDIATELY. IN ANALOGUE WAY, AT THE END OF THE SECOND SEMESTER, THE STUDENT HAS THE POSSIBILITY OF IMMEDIATELY TAKING THE EXAM RELATING TO THE PART OF HEAT TRANSFER. TO ACCESS THE ORAL EXAMS STUDENTS MUST PASS THE WRITTEN TESTS WITH A MINIMUM RATING OF 18/30. THE SCORE OF THE WRITTEN TEST IS DIVIDED INTO FOUR CLASSES (A, B, C, D). THE RESULTS OF THE WRITTEN TEST ARE AVAILABLE ON THE WEB PAGES OF THE PROFESSORS AND THE ORAL EXAMS WILL BE HELD ON AVERAGE SEVEN DAYS DISTANCE FROM THE WRITTEN TEST. THE PURPOSE OF THE WRITTEN TEST IS TO ASSESS THE STUDENT'S OPERATIONAL CAPABILITIES IN ADDRESSING THE PROBLEMS OF APPLIED THERMODYNAMICS, HEAT TRANSER AND ENERGY SYSTEMS. THE WRITTEN TEST OF APPLIED THERMODYNAMICS INCLUDES TWO EXERCISES, TO BE CARRIED OUT IN 2 HOURS. THE FIRST EXERCISE CONCERNS THE THERMODYNAMIC ANALYSIS OF CLOSED OR OPEN SYSTEMS, OR STEAM POWER PLANT OR HEAT PUMPS. THE SECOND EXERCISE IS ABOUT THE RESOLUTION OF A COMBINED HEAT TRANSFER MECHANISM. IN PARTICULAR, IN THE WRITTEN TEST, THE FOLLOWING CALCULATIONS CAN BE REQUESTED: THERMODYNAMIC PROPERTIES, MECHANICAL AND THERMAL POWER, THERMODYNAMIC EFFICIENCY, INTERNAL, EXTERNAL AND GLOBAL ENTROPIC PRODUCTION. FURTHERMORE, THE GRAPHICAL REPRESENTATION OF PHYSICAL PHENOMENA IS REQUIRED WHEN NECESSARY. THE WRITTEN HEAT TRANSFER TEST INCLUDES ONE OR TWO EXERCISES TO BE CARRIED OUT IN 2 HOURS. THE EXERCISES CONCERN COMBINED HEAT EXCHANGE PROBLEMS. FOR THE SOLUTION OF THE EXERCISES IT IS NECESSARY TO USE COMPLEMENTARY DIDACTIC MATERIAL (FORMULAS, DIAGRAMS, TABLES) AVAILABLE ON TEXT OR WEBSITE OF PROF. CUCCURULLO. THE ORAL TEST IS INTENDED TO DEEPEN THE LEVEL OF THEORETICAL KNOWLEDGE, THE AUTONOMY OF ANALYSIS AND JUDGMENT, AS WELL AS THE STUDENT'S EXPOSITIVE CAPABILITIES. DURING THE ORAL EXAMINATION OF APPLIED THERMODYNAMICS, QUESTIONS MAY BE ASKED ABOUT: THE FUNDAMENTAL PRINCIPLES OF THERMODYNAMICS APPLIED TO CLOSED AND OPEN SYSTEMS, THE MAIN MODELS OF THERMODYNAMICS OF THE STATES, IDEAL AND REAL WORKING CYCLES, THE PROPERTIES AND TRANSFORMATIONS OF MOIST AIR. DURING THE ORAL EXAMINATION OF HEAT TRANSFER, QUESTIONS MAY BE ASKED ABOUT ALL THE PLANNED TOPICS. THE MINIMUM LEVEL OF EVALUATION (18/30) IS ATTRIBUTED WHEN THE STUDENT SHOWS A LIMITED KNOWLEDGE OF THE FUNDAMENTAL CONCEPTS OF THERMODYNAMICS AND HEAT TRANSFER, AS WELL AS LOW EXPOSURE CAPABILITY. THE MAXIMUM LEVEL (30/30) IS ATTRIBUTED WHEN THE STUDENT SHOWS A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE FUNDAMENTAL PRINCIPLES OF THE ABOVE ARGUMENTS AND METHODS AND IS ABLE TO SOLVE THE PROPOSED PROBLEMS BY ADOPTING THE MOST APPROPRIATE APPROACH. THE FINAL VOTE IS OBTAINED AS THE AVERAGE OF THE RESULTS ACHIEVED IN APPLIED THERMODYNAMICS AND HEAT TRANSFER. HONORS ARE ATTRIBUTED WHEN THE CANDIDATE EXHIBITS HIGH-LEVEL THEORETICAL AND OPERATIVE SKILLS, AS WELL AS GOOD COMMUNICATION AND AUTONOMOUS PROCESSING CAPABILITIES, EVEN IN AREAS OTHER THAN THOSE PROPOSED BY THE PROFESSORS. |
