ENME 232 - Thermodynamics
Mechanical Engineering

Course Description:

Two hours of lecture and two hours of laboratory per week. Prerequisites: PHYS 260. Introduction to thermodynamics. Thermodynamic properties of matter. First and second law of thermodynamics, cycles, reactions, and mixtures.

Prerequisite(s): PHYS 260

Textbooks

• Thermodynamics, an Engineering Approach, Y. Cengel & M. Boles
  McGraw Hill

Course Objectives

In this course, the student will develop and/or refine the following areas of knowledge:

• Fundamental understanding of how basic laws of thermodynamics and properties of matter describe states of systems and processes involving heat and work.
• Ability to use tabulated charts, state equations, and computer programs to calculate thermophysical properties
• Knowledge of mathematical relationships between basic thermodynamic properties (such as temperature, entropy, enthalpy, etc…)
• Ability to perform energy and mass balances for the design and/or analysis of cycles for steam power plants. Gas turbines, refrigeration cycles, and HVAC systems.

Topics Covered

• Description of matter and phase diagrams
• Concept of work and heat
  
• First law of thermodynamics for open and closed systems
  
• Second law of thermodynamics for open systems, irreversibilities, and Carnot cycle
  
• Entropy and state relations
  
• Cycle analysis
  
• Brayton cycle and modified Brayton cycle
  
• Rankine cycle and its derivatives and vapor compression refrigeration and heat pumps
  
• Ideal gas mixtures, and humid air analysis
  
• Combustion

Class/Laboratory Schedule

• Lectures twice a week at predetermined times
  
• Lab once a week for two hours at a predetermined time

Contribution to professional component

Contributions to course meeting the professional component:
This course should develop the skills necessary to perform energy and mass balances on macroscopic thermal systems. These skills will be applied to power plants, refrigeration cycles, and humid air cycles. Such skills will be critical for students seeking careers in the following industries: utility industry, gas turbine or diesel engine industry, chemical process industry, HVAC industry, etc…

Relationship to program outcomes

This course provides the fundamental basis for energy and mass balances on the macroscopic scale. These principals will be used in future courses on the macroscopic scale to develop governing equations in fluid mechanics, heat transfer, and other disciplines. The laws of thermodynamics express the fundamental concepts of energy conservation and entropy generation, both of which play a critical underpinning for all disciplines of science and engineering.
