Objectives
THE CLASS AIMS AT INTRODUCING THE FUNDAMENTAL EQUATIONS OF FLUID MECHANICS AND AT THE ACQUISITION OF THE ABILITY TO PROPERLY SIZE THOSE FLUID SYSTEMS THAT ARE GOVERNED BY A SIMPLE ONE-DIMENSIONAL BUDGET.
Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES, A BASIC KNOWLEDGE OF MATHEMATICS AND PHYSICS, SUCH AS PROVIDED IN THE CLASSS OF MATHEMATICS I AND II AND PHYSICS I, ARE REQUIRED.
Contents
THE CONTINUOUS DESCRIPTION OF MATTER: LOCAL CONSERVED PROPERTIES OF A CONTINUOUS SYSTEM. BALANCE EQUATIONS. PROPERTIES OF FLUIDS. GENERAL FORM OF MOMENTUM FLUX. MASS AND SURFACES FORCES. THE STRESS TENSOR.
FLUID STATICS: EQUATION OF HYDROSTATICS. MANOMETERS. FORCES ON SUBMERGED SURFACES. FLOATING BODIES.
BALANCE EQUATIONS ON FINITE VOLUMES: THE REYNOLDS TRANSPORT THEOREM. CONSERVATION OF MASS, MOMENTUM AND ANGULAR MOMENTUM. THRUST ON A CONDUIT WITH VARIABLE SECTION AND ON A CURVE. THRUST OF A JET. DIMENSIONAL ANALYSIS.
BALANCE EQUATIONS ON AN INFINITESIMAL VOLUME: FLOW LINES, SURFACES AND FLUX TUBES. THE SUBSTANTIAL DERIVATIVE. NEWTON'S LAW OF VISCOSITY. THE NAVIER-STOKES EQUATIONS. THE EULER EQUATIONS. CURRENT LINES AND THEIR REPRESENTATION. COUETTE AND POISEUILLE FLOW BETWEEN PARALLEL PLATES AND IN A CYLINDRICAL CONDUIT. PLATE SET IN MOTION IMPULSIVELY.
BERNOULLI'S LAW: STATIC PRESSURE, DYNAMIC AND TOTAL. PRESSURE DROP AND PREVALENCE. VENTURI METER AS AND FOR SUCKING.
CURRENT WITH NEGLIGIBLE ACCELERATION: THE THEORY OF REYNOLDS LUBRICATION; THE READ HEAD OF A MAGNETIC DISK. WORK TO CURRENT STOKES AROUND A SPHERE AND A CYLINDER.
POTENTIAL FLOW: FIELDS OBTAINABLE AS A SIMPLE SUPERPOSITION OF WELLS AND SPRINGS. GENERATION OF LIFT. DEFINITION OF THE COEFFICIENTS OF LIFT AND DRAG.
THE BOUNDARY LAYER: CONCEPT OF SIMILARITY. BOUNDARY LAYER ON A FLAT PLATE. CALCULATION OF THE RESISTANCE. QUALITATIVE DESCRIPTION OF THE PHENOMENA ASSOCIATED WITH THE SEPARATION.
TURBULENT FLOW IN DUCTS: PROPERTIES OF TURBULENCE. THE VELOCITY PROFILE. THE LAW OF PRANDTL FRICTION. THE MOODY DIAGRAM. CURRENT IN THE STRAIGHT PIPES AND FITTINGS THROUGH PIPE. BIFURCATIONS. FLOW MEASUREMENTS.
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 THE ACHIEVEMENT OF THE OBJECTIVES WILL BE ASSESSED THROUGH AN OPTIONAL WRITTEN TEST AND AN ORAL INTERVIEW.
