The student will acquire fundamental knowledge on the following topics: - integral and local balance sheets of matter, momentum and energy. - fluid mechanics and momentum transport. - heat transfer by conduction, convection and radiation. - transport of matter with diffusive mechanism and in a turbulent regime. - analogies between transport phenomena, transfer coefficients. At the end of the course the student must be able to phenomenologically and analytically describe the phenomena of transport of matter, energy and momentum by correctly setting the integral and local balance equations of the aforementioned properties.

Basic integral and differential calculus.

Integral proprietary balance: terms of balance equations, balance of matter, reaction rate, momentum balance in fluid systems, energy balance (enthalpy balance, balance of mechanical energy in a fluid, generalized Bernoullli equation). Introduction to the transport of properties: molecular transport in ideal and rarefied gas phases, Fick, Fourier and Newton laws, transport properties (viscosity, thermal conductivity and binary diffusivity of matter), rheological classes, phenomenology of turbulence. Elements of fluid mechanics: fluids in static conditions: Stevin's law, stresses on vessels, buoyancy; fluid dynamics and momentum transport: shear stresses, laminar motion in conduits, friction factor, local and distributed energy dissipation; fluids and solids in relative motion: form coefficient, free fall speed, fluid motion and friction factors in granular beds, fluidization of particle beds. Heat transport: unidirectional conduction in homogeneous and composite solid phases in the absence and in the absence of thermal generation; convective heat transport: forced and natural convection, heat transfer coefficients, series resistances and global coefficient, analogy with the transport of momentum, radiation: absorption and emission of radiant energy, emissivity, Kirchoff's law, black bodies, law of Lambert, emission spectrum, Planck and Wien relations, irradiation between black and gray bodies, visual factors. Matter transport: mass and molar flows, diffusive flow in binary systems, equimolar counter-diffusion, diffusion in stagnant medium, interphase and convective transport: material exchange coefficients, film and penetration models, motive force and global coefficient and controlling resistance, volume coefficient. Local owned and transported balances in a continuous fluid: system observation mode, local balance terms, continuity equation, local momentum and speed range balance, stress tensor, laminar and fit motion equations dimensionless, local energy balance, kinetic energy balance and dissipative terms, Fourier's second law, local material balance in multi-component systems.

The classroom exercises will consist in solving problems of transport phenomena. A laboratory exercise is scheduled whose attendance is mandatory: study of the diffusion of matter in a stagnant fluid and measurement of the dissipation of mechanical energy in moving fluids. Each team will have to prepare a report on the experiments performed.

Exam: Written test;

Modulo di Fenomeni di Trasporto L’esame consiste in due prove scritte. La prima prova ha una durata di 45 minuti e comprende un ampio insieme di quesiti teorici su tutto il programma del corso; per alcuni quesiti sono proposte risposte predeterminate da opzionare, per altri si richiedono brevi dimostrazioni o la rappresentazione di dati/principi in forma grafica. La seconda prova ha una durata di un'ora e 45 minuti e prevede la risoluzione di esercizi di calcolo relativi a bilanci integrali e fenomeni di trasporto. Durante entrambe le prove scritte, gli allievi possono consultare esclusivamente il materiale fornito dal docente e non possono usufruire di altre fonti di informazione quali libri, manuali o appunti. Il voto finale è dato dalla media aritmetica delle votazioni attribuite alle due prove. Modulo di Reattori Chimici L’esame consiste in due prove scritte. La prima prova ha una durata di 45 minuti e comprende un ampio insieme di quesiti teorici su tutto il programma del corso; per alcuni quesiti sono proposte risposte predeterminate da opzionare, per altri si richiedono brevi dimostrazioni o la rappresentazione di dati/principi in forma grafica. La seconda prova ha una durata di un'ora e 45 minuti e prevede la risoluzione di esercizi di bilancio stechiometrico in sistemi aperti e chiusi, dimensionamento ed ottimazione di reattori chimici. Durante entrambe le prove scritte, gli allievi possono consultare esclusivamente il materiale fornito dal docente e non possono usufruire di altre fonti di informazione quali libri, manuali o appunti. Il voto finale è dato dalla media aritmetica delle votazioni attribuite alle due prove.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
