MEEN40010 Engineering Thermodynamics III

Academic Year 2020/2021

This module is intended to advance student learning on topics in Engineering Thermodynamics and Heat Transfer by Radiation. Students taking this module should have already completed modules equivalent to MEEN10050 Energy Engineering, MEEN20050 Heat Transfer, and MEEN30100 Engineering Thermodynamics III.

MODULE TOPICS;
PSYCHROMETRICS (Air Water - Vapour Mixtures)
THERMODYNAMICS IN THE ENVIRONMENT
FUELS, COMBUSTION PROCESSES & INTERNAL COMBUSTION ENGINES
RADIATION HEAT TRANSFER

ESSAY ASSIGNMENT
Separate from the lecture material, each student is required to complete an essay assignment on an individual basis. This is based on a review of published literature from reputable sources and should comprise approximately 2000 (+ 250) words on any one topic chosen freely by the student from an extended list.

Learning Outcomes:

Describe key concepts associated with psychrometry and its application.

Apply the First Law of Thermodynamics to problems involving the combustion of hydrocarbon fuels in steady-state processes.

Explain the operation of boilers and internal combustion engines, with particular emphasis on combustion processes and exhaust emissions formation.

Demonstrate understanding of the principles and application of psychrometry.

Analyse thermal systems where heat transfer by radiation plays a significant role.

Apply thermodynamic principles and laws, to analyse “non-engineering” processes observed in the environment.

Indicative Module Content:

COMBUSTION PROCESSES IN BOILERS AND INTERNAL COMBUSTION ENGINES
Properties of gas mixtures, Properties of Hydrocarbon fuels, Stoichiometry, Enthalpy of Formation, Enthalpy of Combustion, Heating Value of fuels, First Law for Reacting Systems, Adiabatic Flame Temperatures, Dissociation, Emissions formation, Combustion Efficiency. Efficiency of water-heating boilers. Factors affecting performance and efficiencies of internal combustion engines. Combustion processes and exhaust emissions formation in Spark Ignition and Compression Ignition Internal Combustion engines.

PSYCHROMETRICS (Air Water - Vapour Mixtures)
Psychrometric concepts and theory. Thermodynamic properties of moist air-dry bulb temperature, dew point temperature, relative humidity, absolute humidity, adiabatic saturation temperature, specific enthalpy. Thermodynamic wet bulb temperature. The psychrometric chart.

RADIATION HEAT TRANSFER
Radiation Fundamentals - Introduction and Applications.
Radiative Properties of Surfaces, Spectral Blackbody Emissive Power, Wien’s Displacement Law, Stefan-Boltzmann Law. Radiation Exchange between Surfaces - View factors, Blackbody radiation exchange. Gray surface radiation exchange. Radiation shields.

THERMODYNAMICS IN THE ENVIRONMENT

Approaches to Teaching and Learning:
The module will delivered primarily as a programme of approximately 30 formal lectures with blended delivery format where some are delivered face-to-face and syncronously and others offered online only.

Also, each student is required to complete an essay assignment on an individual basis. This is based on a review of published literature from reputable sources and should comprise approximately 2000 (+ 250) words on any one topic chosen freely by the student from an extended list. The intention is to facilitate independent and more in-depth learning on a topic that is relevant to the module. In doing this, students should become familiar with how to source and interpret some reputable / refereed publications that discuss the current state of the art and possibly identify future development prospects. Writing a concise summary in the student’s own words is an important skill that will most likely be needed in the course of a future engineering career.

 
Requirements, Exclusions and Recommendations
Learning Requirements:

Students taking this module should have previous education in Engineering Thermodynamics. Ideally, students would have already completed MEEN30100 Engineering Thermodynamics II.
