Topics include scaling laws, heat and mass transfer via diffusion, convection, conduction, and radiation, laminar and turbulent flows, single-phase and phase-change, as well as introduction surface fabrication and functionalization as well as wettability characterization and recent studies. |
| Course description |
Week 1 - Introduction, conservation equations and rate laws mapping earlier courses:
An introduction to the different mechanisms of heat and mass transfer and applicatoins viewed in earlier courses of Heat, Mass and Momentum Transfer 3 (CHEE09013), Fluid Mechanics 2 (SCEE08003) and Chemical Engineering Thermodynamics 2 (CHEE08009), will position the student with the background and refreshed concepts necessary for the course. Special attention will be paid to mass and heat transport conservation equations & to rate laws governing transport. Extend these to include theory, scaling, governing forces, wettability including surface tension, contact angle hysteresis, surface energy, at micro-/nano-scale.
Week 2 - Conduction heat transfer:
Steady 1D heat transfer with constant and variable thermal conductivity. Extended to steady 2D heat transfer on structured surfaces. Concept of thermal resistance applied to a 1D and a 2D finite bodiesesis, surface energy, at the micro-/nano-scale.
Week 3 - Convective heat transfer:
Steady 1D heat transfer with constant and variable interfacial conductivity. Extended to steady 2D heat transfer on structured surfaces. Concepts of interfacial resistance applied to a 1D and a 2D finite bodies.
Week 4 - Laminar and turbulent Flows: Overlap Fluid Mech 4 (Prash) To incorporate Multiphase Flows
Laminar boundary layers, fluids problem (D-Alembert's Paradox), heat transfer problem, Von Karman momentum and energy integral techniques, laminar internal flows and natural convection, turbulent boundary layers, the fluids problem, the heat transfer problem, flow over a flat plate, flow over cylinders and spheres, Stokes flow.
Week 5 - Conduction and convective heat transfer with phase change:
Transient 1D heat transfer with constant and variable thermal conductivity. Extended to transient 2D heat transfer on structured surfaces at different scales. The concept of thermal resistance and interfacial resistance applied to a 1D and a 2D bodies with moving interfacial resistance and phase change.
Week 6 - Condensation (UN SDG 6 & 7):
Concepts secured during Week 1 to Week 5 will be applied for dynamic and steady state laminar and turbulent filmwise, and dropwise condensation on smooth and on micro- and nano-structured surfaces. Framework and background to be introduced include theoretical advances and experimental findings at the micro-/nano-scale including hydrophobic and superhydrophobic surfaces, bioinspired surfaces, lubricant infused surfaces, thermosiphons, etc.
Week 7 - Boiling/Evaporation (UN SDG 6 & 7):
Concepts secured during Week 1 to Week 5 will be applied for dynamic and steady state film evaporation, dropwise evaporation and boiling on smooth and on micro- and nano-structured surfaces. Framework and background to be introduced include recent theoretical advances and experimental findings at the micro-/nano-scale with focus on enhance mass and heat transport in spray driers, thermosiphons, micro-channels, and solar evaporators, amongst others.
Week 8 - Micro-/nano-fabrication functionalisation and characterisation: Case studies to be revised and/or maybe implemented in earlier weeks
Introduction to micro-/nano-fabrication and functionalisation techniques and processes including opportunities and relevant works in fluid transport, bioinspired surfaces, atmospheric-mediated superhydrophobicity of metallic surfaces, and others. In addition, advanced measurement, characterisation and observation techniques, at the micro- and the nano-scale, are also reviewed and introduced.
Week 9 - Multi-component Systems (UN SDG 6 & 7): To incorporate Multiphase Flows Case studies to be revised and/or maybe implemented in earlier weeks
Traditionally, due to its complexity, the fundamentals of dropwise evaporation and dropwise condensation are introduced and formulated for a single isolated drop. However in real applications, drops are found in populations and there is a clear and strong heat and mass transfer interplay between two or more finite bodies undergoing phase-change on smooth and on structured solid surfaces, which is the scope of this module.
Week 10 - Energy Systems (UN SDG 6 & 7): Case studies to be revised and/or maybe implemented in earlier weeks
Real systems benefiting from recent advances on micro- and nano-fabrication with consequent enhanced heat and mass transfer performance are introduced here. The more accurate modelling and characterisation of the heat and mass transfer mechanisms taking place during phase-change at the micro- and at the nano-scale are also presented and discussed.
