EUR-ACE’S EXPECTED LEARNING OUTCOMES THE COURSE AIMS TO PROVIDE ADVANCED KNOWLEDGE OF TRANSPORT PHENOMENA (MOMENTUM, ENERGY, MASS) OF INTEREST IN FOOD ENGINEERING AND FOOD PROCESSING. STEADY-STATE AND TRANSIENT PROCESSES WILL BE ADDRESSED, AS WELL AS THE ROLE PLAYED BY THE TRANSPORT THERMO-PHYSICAL PROPERTIES OF FOODS. KNOWLEDGE AND UNDERSTANDING THE STUDENTS WILL ACQUIRE KNOWLEDGE ON TRANSPORT PHENOMENA FUNDAMENTALS, CONSTITUTIVE EQUATIONS, EQUATIONS OF CHANGE (MOMENTUM, ENERGY, MASS), TO BE APPLIED TO FOOD SYSTEMS, IN STEADY AND UN-STEADY STATE. THE STUDENTS WILL ACQUIRE KNOWLEDGE ON MULTI-PHYSICS FOOD PROCESSES, RHEOLOGY AND RHEOMETRY: NEWTONIAN AND NON-NEWTONIAN FLUIDS, VISCOELASTICITY. MEASUREMENTS OF ENGINEERING PROPERTIES OF FOOD MATERIALS. THE STUDENTS WILL LEARN HOW TO RELATE TRANSPORT PROPERTIES TO FOOD COMPOSITION. ENGINEERING ANALYSIS ABILITY TO PROPERLY APPLY AND ADAPT THE EQUATIONS OF CHANGE WITH RESPECT TO SPECIFIC APPLICATIONS TO FOOD PROCESSES. ENGINEERING DESIGN ABILITY TO PROPERLY SOLVE EQUATION OF CHANGES IN APPLICATIONS TO FOOD PROCESSES. MAKING JUDGMENTS - ENGINEERING PRACTICE: MAKE USE OF THE RESULTS OF SPECIFIC TRANSPORT PROPERTY MEASUREMENTS TO PREDICT THE BEHAVIOR OF FOOD MATERIALS. COMMUNICATION SKILLS – TRANSVERSAL SKILLS: THE STUDENT WILL BE ABLE TO PRESENT, IN A CONCISE WAY, THE MOST RELEVANT ASPECTS OF A TRANSPORT PHENOMENA PROBLEM IN FOOD PROCESSES, FROM MATHEMATICAL DESCRIPTION OF PHENOMENA, TO DISCUSSION OF INITIAL AND BOUNDARY CONDITIONS, UP TO SOLUTION FORMS. THE ACQUIRED COMMUNICATION SKILLS WILL ALLOW THE STUDENT TO INTERACT WITH OTHER PROFESSIONALS OF DIFFERENT BACKGROUND, FROM FOOD TECHNOLOGISTS AND FOOD SCIENTISTS TO PRODUCTION MANAGERS. LEARNING SKILLS – TRANSVERSAL SKILLS: THE STUDENT WILL ACQUIRE A METHOD OF ANALYSIS OF TRANSPORT PHENOMENA THAT CAN BE APPLIED IN CONTEXTS EVEN DIFFERENT THAN THE ONES PRESENTED DURING THE COURSE; THE ACQUIRED METHODOLOGY WILL ALLOW THE STUDENT TO PERFORM, INDEPENDENTLY OR IN TEAM, DEEP ANALYSIS OF FOOD PROCESSES, COUPLING DIFFERENT TRANSPORT PHENOMENA EVEN IN COMPLEX MULTI-PHYSICS CONTEXT. |

|---|---|
| THE EVALUATION WILL BE CARRIED OUT BY A WRITTEN TEST AND AN ORAL INTERVIEW. THE ESSENTIAL CONDITION TO PASS THE EXAM IS THE ABILITY TO IDENTIFY, IN A GIVEN PROBLEM, THE MOST RELEVANT PHENOMENA AND TO WRITE THE PROPER MODEL EQUATIONS. THE FINAL MARK, BETWEEN EIGHTEEN AND THIRTY CUM LAUDE, DEPENDS ON THE DEMONSTRATED ABILITY TO MASTER THE COURSE’S ISSUES. |
