Prerequisite Modules:
Rationale and Purpose of the Module:
The rationale of this module is to augment the choice of electives on the one year MSc in Mechanical Engineering and in year 5 of the integrated BE/ME in Mechanical Engineering with a module that covers heat and mass transfer phenomena of relevance to a wide range of engineering applications - energy systems, buildings, human comfort, chemical processes, and transport (automotive / aerospace).
The purpose of the module is to cover the physical principles and engineering science associated with heat and mass transfer, encompassing conduction, convection, radiation, phase change, and diffusive and convective mass transfer.
Syllabus:
Overview of heat and mass transfer; modes of heat transfer; thermal resistance; conductive heat transfer; thermal conductivity; Fourier's Law and multi-dimensional steady-state conduction; transient conduction - the lumped capacity approximation and exact methods; analytical and numerical techniques for conduction; Newton's Law and the heat transfer coefficient; thermophysical properties of fluids; boundary layers and dimensionless groups; correlations for forced convection including external and internal forced convection, and natural convection, for laminar and turbulent flows; mass transfer analogies; diffusive and convective mass transfer; boiling heat transfer, condensation and evaporation; interfacial phenomena; humidity; heat exchangers - the overall heat transfer coefficient and the log-mean temperature difference, and the effectiveness Number of Transfer Units (NTU) method; principles of radiation - blackbody radiation and Planck's distribution; surface properties - emissivity, absorbtivity, reflectivity and transmissivity; Kirchoff's Law; view factors and radiation networks; solar and environmental radiation; radiation shields; and an overview of measurement techniques for temperature, flow, pressure, humidity and concentration.
Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
- An understanding of heat and mass transfer artifacts and their existing and emerging applications.
- Knowledge of fluids and materials, and their thermophysical properties for applications in heat and mass transfer systems.
- Comprehension of the governing equations for conductive, diffusive, convective (heat and mass) and radiative transfer, and related dimensionless groups for scaling analysis.
- A working knowledge of analytical and numerical techniques for heat and mass transfer applications.
Hands-on experience of measurement techniques for temperature, flow, pressure-drop and concentration (humidity).
Affective (Attitudes and Values)
- The ability to co-operate in small groups during laboratory experiments.
- An appreciation of the state-of-the-art and the wide-ranging potential for innovations enabled by heat and mass transfer phenomena.
Psychomotor (Physical Skills)
- The ability to conduct experimental investigation of heat and mass transfer phenomena - for example, parallel and cross-flow heat exchangers with liquid and air flows, including manometry, thermometry and qualitative flow visualisation - will exercise dexterity and hand-eye coordination.
How the Module will be Taught and what will be the Learning Experiences of the Students:
The module will feature lectures, tutorials and a set of laboratory exercises on a range of heat and mass transfer phenomena which will be conducted in small groups. The laboratories will take place within the School of Engineering, and the phenomena under investigation will be drawn from up-to-date research at UL (for example, heat pipes for thermal management applications). UL's graduate attributes will be strongly developed through the laboratory exercises, which will involve group work and written / oral presentation of results (proactive, creative, responsible, articulate, collaborative & knowledgeable).
