Thermodynamics of Energy Conversion Systems



Nicolas HudonDupuis Hall 533-2787



Course Description

This course is an introduction to thermodynamics for chemical engineering systems analysis. The principles arising from First and Second laws of thermodynamics will be applied to the solution of mass, energy, and entropy balances for homogeneous closed and open systems. Properties of ideal gases and real fluids will be derived from Equations of State and applied in the analysis of simple flow processes.  The students will compute efficiencies and coefficients of performance for energy production, conversion, and storage systems.  The impacts of energy process design choices on efficiency, performance, and sustainability will be measured through exergy analysis.

Prerequisites CHEE 221 (or MINE 201).

Objectives and Outcomes

This course reinforces the concept of mass and energy balances viewed in CHEE 221 by applying the First and Second laws of thermodynamics to closed and open systems.  Consequences of thermodynamics in the computation of real fluid quantities in the analysis of key process components are derived.  Thermodynamic efficiency and coefficient of performance are used in the analysis of energy production, conversion, and storage processes.  Thermodynamic analysis is developed for gas, steam, combined cycles, as well as refrigeration systems and air conditioning.  Impacts of design choices and operation conditions on efficiency and performance are emphasized, with the aim of improving energy processes sustainability.

The specific course learning outcomes include:

CLO1 Apply the fundamental concepts of thermodynamics to solve material, energy, and entropy balances for process components, open or closed. KB-Thermo(a)
CLO2 Apply the First Law of Thermodynamics to compute heat, work, and changes in internal energy and enthalpy for the analysis of open or closed homogeneous systems undergoing reversible or irreversible processes. KB-Thermo(a)
CLO3 Apply the Second Law of Thermodynamics and the concept of entropy production to the analysis of reversible or irreversible processes. KB-Thermo(a)
CLO4 Establish the relationships between internal energy, enthalpy, entropy, Gibbs and Helmholtz free energies potentials. Relate these potentials to heat capacities, measurable variables, and macroscopic quantities.  Use Maxwell's relations. KB-Thermo(a)

CLO5 Use equations of state for gases and liquids to determine changes in properties of fluids and apply these equations to solve  material, energy, and entropy balances for process components, open or closed. KB-Thermo(a)
CLO6 Describe and analyze the performance and efficiency of simple engines, Rankine cycles, Brayton cycles, and refrigeration cycles. Apply the combined material, energy, entropy, and exergy balance equations to solve process flow problems. KB-Thermo(b)

The course outcomes are mapped to the following program indicators at a 2nd year level:

Knowledge Base for Engineering (KB):

  • KB-Thermo(a) Applies laws of thermodynamics, identifies thermodynamic and PVT properties and applies equations of state to describe fluid behaviour and construct phase diagrams for single and multi-component systems
  • KB-Thermo(b) Analyzes thermodynamic cycles and process components and performs the relevant calculations

Problem Analysis (CLO 4):

  • PA-Formulate Develop appropriate frameworks for solving complex engineering problems.

Relevance to the Program

  • The course expands the notion of mass and energy balances introduced in CHEE 221 and developed concurrently in CHEE 222 by introducing the First and Second laws of thermodynamics in the analysis of simple chemical processes, with an emphasis on energy production, conversion, and storage systems.
  • A rigorous formulation of thermodynamic concepts and property of fluids is developed as a pre-requisite to CHEE 311 where the concepts of thermal, mechanical, and chemical equilibrium are developed further.  The concepts arising from this thermodynamic framework will also be used in CHEE 321.
  • Impacts of design choices on efficiency and performance and thermodynamic limitations in the design of energy conversion systems introduced in this course will be reinforced in CHEE 330.
