| KNOWLEDGE AND UNDERSTANDING: BALANCE EQUATIONS IN DIFFERENTIAL AND INTEGRAL FORM FOR MASS, MOMENTUM, ENERGY AND CHEMICAL SPECIES. THE STRESS TENSOR AND ITS PROPERTIES. NEWTONIAN, NON-NEWTONIAN AND VISCOELASTIC FLUIDS. SOLUTION OF MOMENTUM BALANCE EQUATIONS WITH MORE THAN ONE INDEPENDENT VARIABLE. STREAM AND VELOCITY POTENTIAL FUNCTIONS. TEMPERATURE PROFILES IN SYSTEMS DEPENDENT ON TWO VARIABLES. ANALOGIES BETWEEN HEAT AND MASS TRANSPORT AND MAIN DIMENSIONLESS NUMBERS. TRANSPORT PROPERTIES IN THE TURBULENT REGIME. THEORIES FOR THE DESCRIPTION OF THE COEFFICIENTS OF HEAT AND MASS EXCHANGE. TRANSPORT OF CHEMICAL SPECIES WITH HOMOGENEOUS CHEMICAL REACTION. APPLIED KNOWLEDGE AND UNDERSTANDING - ENGINEERING ANALYSIS: THE STUDENT WILL BE ABLE TO UNDERSTAND THE UNDERLYING MECHANISMS OF TRANSPORT PHENOMENA AND TO BREAK DOWN COMPLEX PROBLEMS INTO SIMPLER PROBLEMS BEING AWARE OF THE SIMPLIFICATIONS AND APPROXIMATIONS. THE STUDENT WILL BE ABLE TO FIND SOLUTIONS TO COMPLEX VARIABLE PROBLEMS OF SEVERAL VARIABLES, INTRODUCING THE NECESSARY SIMPLIFICATIONS BASED FOR EXAMPLE ON THE ANALYSIS OF ORDERS OF MAGNITUDE. APPLIED KNOWLEDGE AND UNDERSTANDING - ENGINEERING DESIGN ABILITY TO WRITE AND SOLVE IN AN APPROPRIATE WAY, ALSO WITH THE AID OF A COMPUTER, THE BALANCE EQUATIONS WITH THE APPROPRIATE BOUNDARY CONDITIONS, FOR PROBLEMS OF TRANSPORT OF MASS, MOMENTUM AND HEAT. MAKING JUDGMENTS - ENGINEERING PRACTICE: DURING THE COURSE, THE STUDENT WILL BE ABLE TO USE A SOFTWARE FOR THE SOLUTION OF TRANSPORT EQUATIONS. TRANSVERSAL SKILLS - COMMUNICATION SKILLS: CAPACITY TO WORK IN GROUPS AND TO PRESENT WITH THE HELP OF A COMPUTER THE SOLUTION TO A MOMENTUM, HEAT OR MASS TRANSPORT PROBLEM TRANSVERSAL SKILLS - ABILITY TO LEARN: KNOWING HOW TO APPLY THEIR KNOWLEDGE TO CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE, AND DEEPEN THE TOPICS USING MATERIALS OTHER THAN THOSE PROPOSED. |

| Teaching Methods | |
|---|---|
| THE COURSE CONSISTS IN LESSONS, EXERCISES AND APPLICATIONS AT THE COMPUTER. AT THE BEGINNING OF THE COURSE A PROJECT IS ASSIGNED TO STUDENTS, DIVIDED IN WORKING GROUPS, CONSISTING IN APPROACHING A PROBLEM OF TRANSPORT PHENOMENA AND RESOLVING THE RESULTING EQUATIONS WITH A FINITE ELEMENT PROGRAM. SLIDES OF THE LESSONS AND SOME WORKED EXERCISES ARE MADE AVAILABLE ON THE WEBSITE WWW.POLYMERTECHNOLOGY.UNISA.IT |
| Verification of learning | |
|---|---|
| THE ASSESSMENT OF THE GOALS' ACHIEVEMENT WILL BE DONE THROUGH A WRITTEN TEST AND ORAL INTERVIEW. IS AN ESSENTIAL CONDITION FOR PASSING THE EXAM THE ABILITY TO CORRECTLY FORMULATE OF DIFFERENTIAL MOMENTUM, ENERGY AND MASS BALANCES, THE ANALYTICAL SOLUTION OF PROBLEMS OF MOLECULAR TRANSPORT DEPENDING ON TIME FOR ONE-dimensional SYSTEMS, THE CORRECT DETERMINATION OF THE CHARACTERISTICS TIMES DIMENSIONLESS NUMBERS INVOLVED. THE STUDENT REACHES THE LEVEL OF EXCELLENCE ONCE HE PROVES TO BE ABLE TO DEAL WITH UNUSUAL PROBLEMS UNUSUAL, NOT EXPRESSLY DEALT DURING THE LESSONS, REACHING A COMPLETE SOLUTION IN ALL THE PARTS. THE FINAL MARK WILL DEPEND ON THE DEGREE OF MATURITY ACQUIRED ON THE COURSE CONTENTS AND ON THE METHODOLOGY EXPOSED IN THE COURSE, TAKING INTO ACCOUNT THE QUALITY OF WRITTEN TEST, PROJECT PRESENTATION AND COLLOQIUM. |
