Learning outcomes

The course aims at providing the basic knowledge and the specialized methodologies of general thermodynamics and chemical thermodynamics, for the thermodynamic analysis of processes, the predictive assessment of thermodynamic properties of pure substances, mixtures, and chemical and phase equilibria.

Course contents

Brief recall on:

• - basic thermodynamic quantities, Enthalpy, Internal Energy specific heat etc...
• - the First Law of Thermodynamics and on its use to solve simple thermodynamic problems.
• - Second Law of Thermodynamics and its role in determining: i) the constitutive equations for simple and complex fluids (Gibbs-Maxwell relationships) ii) Analysis of thermodynamic equilibrium and stability

Introduction to mathematical models for the analysis of system properties.

• Corresponding state theory, Cubic Equations of State, Generalized Correlations for Gases & Liquids
• Example of application to the solution of simple thermodynamic problems

Analysis of the constraints guiding the energy conversions:

• Ideal and Lost Work, Minimum work required/Maximum obtainable work; Exergy.
• the thermodynamic analysis of processes. Applications to Compressible Flows and Compressors, to Power Cycles and Refrigeration cycles

 

Thermodynamics of Multicomponent systems:

• Ideal and non ideal mixture: excess properties and their calculation.
• Energy balance for non ideal mixture, mixing enthalpy and enthalpy concentration charts
• Thermodynamic approaches for the description of non ideal mixtures: fugacity, activity and activity coefficient and their calculation.
• General multiphase equilibrium i) Vapor-Liquid Equilibrium: Qualitative behavior and Ideal models. ii) Liquid-liquid and Vapor-Liquid-liquid Equilibrium –
• GE model for the analysis of non ideal systems
• Henry's law for the analysis of gas-liquid and solid liquid equilibrium
• Extension of EoS to the description of mixtures, application to Polymer Solution
• Chemical Reaction Equilibrium i)  derivation of general equilibrium relationship and analysis of Temperature and pressure effects ii) Example of solution for non ideal systems, system involving pure solid phases, system involving also the presence of a liquid phase, iii) Multiple Reactions systems.

Lectures

Assessment methods

The course assessment will be based on a written and possibly an oral exam which can be requested by student interested in improving their final grade.

The written exam will be divided in 2 parts: the first one is focused on open questions on the theoretical parts of the course. the second one which will request the solution of 1 or 2 exercises involving pure substances and mixtures thermodynamics.

In the second part the use of personal materials and textbook is allowed, the use of laptop is permitted even if not  strictly necessary.

Student which final score above 17 can register their grade directly. All student with grades above 15 may request an oral part to improve their grade. 

The oral exam will be usually based on two questions focused on the discussion on both applications and theoretical backgrounds. Student not able to pass the exam will be requested to make a new written exam. 

Teaching tools

The slide presented during the lesson as well as other supporting materials (exercise, older exam and so on) will be made available online in the course website before the beginning of the lesson and during the lesson in case of particular needs or update.
