Objectives
THE AIM OF THE COURSE OF THERMODYNAMICS AND HEAT TRANSFER IS TO PROVIDE FOR THE KNOWLEDGE OF THE MAIN CONCEPTS OF THERMODYNAMICS, ENERGY CONVERSION SYSTEMS AND HEAT TRANSFER. THE COURSE, LOCATED ON THE SECOND YEAR, IS OF 12 CREDITS WITH A DURATION ON TWO SEMESTERS. THE FIRST HALF IS DEVOTED TO THERMODYNAMICS AND THE SECOND TO HEAT TRANSFER.
IN THE FIRST SEMESTER THE MAIN OBJECTIVE IS THE STUDY OF THERMODYNAMICS, FIRST WITH THE APPROACH OF THE FUNDAMENTAL CONCEPTS OF THE BASIC TERMODINAMICS (I AND II LAW OF TERMODYNAMICS) AND AFTER THE MAIN TERMODYNAMICS APPLICATIONS REFERRING TO THE APPLICATIONS OF THE I AND II LAW OF THERMODYNAMICS TO COMPONENTS OF POWER PLANT, HEAT PUMP AND REFRIGERATION SYSTEM.
THE SECOND SEMESTER IS SUBJECT TO THE STUDY OF HEAT TRANSFER AND ITS AIM IS TO STUDY THE MATHEMATICAL PHYSICAL BASIS OF THE DISCIPLINE. THEREFORE, AFTER DEFINITING THE THREE MAIN MODES OF THERMAL EXCHANGE AND DISCUSSED THE CORRESPONDING CONSTITUTIONAL EQUATIONS, THE COURSE ALLOWS TO EDUCATE FOR TRANSFORMING THERMAL PROBLEMS IN FORMAL LANGUAGE AND TO STUDY THE ANALYTICAL SOLUTION ALSO APPROXIMATE.
THE FIRST PART OF THE COURSE WILL BE GIVEN BY PROF. RENNO, THE SECOND BY PROF. CUCCURULLO. OTHER INFORMATION CAN BE FOUND HERE:

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
DURING THE COURSE LESSONS AND EXERCISES ARE PROVIDED IN THE CLASSROOM. SELECTED EXERCISES ARE ASSIGNED TO THE STUDENTS IN ORDER TO IMPROVE THE KNOWLEDGE OF THERMODYNAMICS, ENERGY CONVERSION SYSTEMS AND HEAT TRANSFER
Verification of learning
THE ACHIEVEMENT OF THE PREFIXED OBJECTIVES WILL BE REALIZED BY WRITTEN TEST AND ORAL INTERVIEW. THE LATTER IS TO BE HELD NECESSARILY IN THE SAME SESSION IN WHICH THE WRITTEN TEST IS PASSED AND IS TYPICALLY SCHEDULED SEVEN DAYS AFTER THE WRITTEN TEST. IN PARTICULAR, IT IS AIMED TO EVALUATE THE CAPABILITY OF THE STUDENT IN APPROACHING, WITH CRITICAL SENSE AND MATURITY, PROBLEMS TYPICAL OF APPLIED THERMODYNAMICS AND HEAT TRANSFER. WRITTEN TESTS MAY INCLUDE QUESTIONS OPEN AND STRUCTURED SEMI-STRUCTURED TESTS IN ADDITION TO VARIOUS TYPES OF EXERCISES.
