Teaching description
Knowledge of transport phenomena and polymer physics and chemistry.
This course is aimed to apply the basic knowledge of transport phenomena to the mathematical modeling of processing of composite materials. Competences on thermosetting polymer matrices, their reactivity and the kinetics of curing are also provided. Basic elements of finite element (FE) numerical solution of heat balance equations is provided. The optimization of composite processing is performed adopting a FE tool. In the last part of the course sorption and mass diffusion in polymers is analyzed as an application of the basic knowledge of transport phenomena
Knowledge and understanding:
The course provides the basis of knowledge to understand and solve complex new problems in materials processing and in mass and heat diffusion, applying ideas often in a research context
Applying knowledge and understanding
The student will be able to solve heat and mass balances, applied to materials processing, using approximate solution or numerical methods. A multidisciplinary approach is presented accounting for chemical, materials and mechanical engineering aspects.
Making judgements
Dimensionless and approximate methods are presented in order to promote the judgement and evaluation capabilities of the students
Communication
The course promotes the development of the following skills of the student: ability to expose in precise and formal terms an abstract model of concrete problems, identifying the salient characteristics of them and discarding the inessential characteristics; ability to describe and analyze an efficient solution for the problem under consideration.
Learning skills
Autonomous learning is promoted thanks to the use of: different books and slides, numerical methods, homework exercise to be solved in groups of two
Lessons, practice with a Finite Element program for the solution of differential equations, visit to an industrial plant. Self evaluation tests with Kahoots after every topic
Interview after a homework . A homework regarding modeling topics, and an associated finite element solution of the related differential equations, is assigned to students. During the exams the homework is discussed and if the results are satisfactory an interview is started with questions regarding the main topics of the course
Assessments dates available at ing.unisalento.it. The assessment includes the discussion of an assignment followed by an interview
