B6341 - MODELLING TOOLS FOR PROCESS ENGINEERING ANALYSIS

Conoscenze e abilità da conseguire

The course will build on previous background on mass, heat and momentum transport to give to students more advance tools for the analysis of real process engineering problems of interest for offshore application, related for example to product purification, decarbonization, reduction of waste and increase of efficiency. In particular the course will provide the students with advanced modelling tools for analysing momentum, energy and mass transport in multi-dimensional problems under different flow regimes as well as mathematical model to describe and/or predict the thermodynamic behaviour of pure substances and non-ideal mixtures. Technologies and processes for offshore energy production Introduction to and training in sustainable design of production processes in the offshore sector. Application of knowledge in mass and energy balances, thermodynamics, fluid dynamics, heat transfer, unit operations to process selection and simulation in offshore energy processes. Analysis of the role of technical constraints, economic factors, environmental impact and safety in process design.

Contenuti

The course is divided in two modules covering respectively thermodynamic and transport modelling.

Module 1
The first module will focus on modelling tools which can help the analysis of thermodynamic behavior of complex systems. In particular starting from the corresponding state theory, the use of equation of state (e.g van der Waals and generalized cubic equation of states) and of activity coefficient models ( e.g , an Laar, Wilson and NRTL models) will be presented to solve different types of thermodynamic problems overcoming limitations imposed by the use of ideal gas EoS or ideal mixture approximation and reducing the need of external data for the solution.

Module 2
The second module will first provide knowledge about tools from Linear Algebra which are essential for the representation of mass, momentum and energy fluxes in 3D space and then the local form of general balance and specific constitutive equations will be derived. The student will learn how to develop consistent mathematical models for the description of mass, momentum and energy transport processes, in terms of field equations and boundary conditions. The student will then be trained to recognize characteristics of the solutions of corresponding models from the structure of governing equations, to be able to anticipate characteristic time/space values, as well as specific scaling laws in the problem. Abilities that students developed in the above modelling analysis will be finally applied to examples of phenomena and processes of offshore engineering

Metodi didattici

Lessons in presence with the help of slides and other materials

Modalità di verifica e valutazione dell'apprendimento

The assessment will be based on a written test involving both exercise and open (or multiple-choice) question covering the different topics treated during the course.

In general, at least one exercise and one open question (or a set of multiple-choice questions) will be considered for each module of the course

Exam dates (6 throughout the year) are published on Almaesami and the student must register in advance to take part in the exam.

If the student fails the exam, s/he can retry on a subsequent date.

If the student passes the exam, s/he can accept the score, or reject it and retry the exam on a subsequent date. A positive score can only be rejected once, the second (most recent) positive score will be registered.

The student has the possibility to withdraw from the exam before the end, if s/he prefers not to be assessed.

Strumenti a supporto della didattica

Lectures, slides, equation tables, meetings with professor (upon request) during office hours
