| Objectives | |
|---|---|
| THE COURSE PURPORTS TO PROVIDE KNOWLEDGE ON GENERAL SCIENTIFIC CONTENTS AND METHODOLOGICAL-OPERATIONAL ASPECTS OF FLUID MECHANICS. IN PARTICULAR, THE COURSE AIMS TO PROVIDE KNOWLEDGE OF THE FUNDAMENTAL EQUATIONS GOVERNING THE MOTION OF A FLUID AND THE ACQUISITION OF THE ABILITY TO PROPERLY SIZE THOSE FLUID SYSTEMS THAT ARE GOVERNED BY A SIMPLE ONE-DIMENSIONAL BALANCE. THE MAIN KNOWLEDGE ACQUIRED DURING THE COURSE WILL BE: • DESCRIPTION OF THE MATTER AS A CONTINUUM • FLUID STATICS • BALANCE EQUATIONS ON A FINITE VOLUME, • BALANCE EQUATIONS ON AN INFINITESIMAL VOLUME • BERNOULLI'S LAW • CURRENTS WITH NEGLIGIBLE ACCELERATION • POTENTIAL FLOW • BOUNDARY LAYER FLOW • TURBULENT FLOW IN DUCTS. THE MAIN SKILLS ACQUIRED BY STUDENTS DURING THE COURSE WILL BE: • TO PROPERLY SIZE THOSE FLUID SYSTEMS WHOSE CHARACTERISTICS DERIVE FROM A SIMPLE ONE-DIMENSIONAL BALANCE • TO DETERMINE FORCES AND TORQUES ACTING ON SYSTEMS IN CONTACT WITH A FLUID AT REST OR IN MOTION. • TO DERIVE THE BASIC DIMENSIONLESS PARAMETERS THAT DETERMINE THE BEHAVIOUR AND THE PERFORMANCES OF A FLUID SYSTEM. • TO OBTAIN AN OVERVIEW OF THE DIFFERENT BEHAVIOURS THAT A FLUID CAN MANIFEST, DESCRIBING IN A SIMPLIFIED MANNER (BOTH QUALITATIVELY AND QUANTITATIVELY) THEIR MAIN FEATURES. • TO ACQUIRE AND USE A SCIENTIFIC TERMINOLOGY APPROPRIATE TO DESCRIBING AND MODELLING A FLUID SYSTEM. |
| Prerequisites | |

| Teaching Methods | |
|---|---|
| THE COURSE IS BASED ON LECTURES, CLASSROOM EXERCISES AND MOVIE PROJECTIONS. CLASSROOM EXERCISES ARE USUALLY RELATED TO THE THEORY AND ARE CARRIED OUT WITH THE INVOLVEMENT OF THE STUDENTS. SHORT MOVIES CONCERNING EXPERIMENTS ARE PROJECTED FOR ILLUSTRATIVE PURPOSES TO BETTER UNDERLINE SOME PRACTICAL AND THEORETICAL ASPECTS OF THE COVERED TOPICS. |
| Verification of learning | |
|---|---|
| THE ACHIEVEMENT OF THE OBJECTIVES WILL BE ASSESSED THROUGH A WRITTEN TEST LASTING ABOUT TWO HOURS, COMPRISED OF BOTH THE ANSWER TO THEORETICAL QUIZZES AND THE SOLUTION OF EXERCISES. INTEGRAL TO THE EVALUATION, WHERE TAKEN, WILL BE TESTS OF THE SAME FORMAT CARRIED OUT DURING THE CLASS. |
