How can you reduce the energy loss of your home? What is the underlying science of energy loss in pipes? Which heat and mass transfer problems do we have to tackle to make consumer products?
In this engineering course, you will learn about the engineering principles that play an important role in all of these and more phenomena. You will learn about microbalances, radiation, convection, diffusion and more and their applications in everyday life.
This advanced course is for engineers who want to refresh their knowledge, engineering students who are eager to learn more about heat/mass transport and for all who have fun in explaining the science of phenomena in nature.
- Microbalance and an overview of heat conduction and diffusion problems
- To calculate the pressure loss over pipe and pipeline systems
- The definition of convective transport of heat and mass transfer and how you can apply it
- The distribution of components over immiscible phase and the importance of this distribution for many applications
- The difference in flow behaviour of water and toothpaste and the reasons of this difference
- The definitions of heat radiation, black and grey bodies
- How to calculate the heat loss by radiation
Специальные требования
- We strongly recommend TP101x as a prerequisite for this MOOC, but if you are familiar with mass and heat transport phenomena you will be able to follow the course as well
- Basic knowledge of calculus (derivative, integral, simple differential equations)
- Thermodynamics (concepts of first and second law, properties of fluids, heat effects)
- High school physics
Программа
Week 1: Microbalances in Transport Phenomena
- A short summary of microbalances in tubular reactors (plug flow), with in parallel the introduction of the ‘microbalance’ for subjects which were not covered in TP101x Transport Phenomena, such as Fourier and Fick's law in different geometries (diffusion through membranes).
Week 2: The momentum balance
- The momentum balance is a new subject and can be combined with mass and energy balance.
- Introduction of the pressure drop by means of a force balance and the definition of the friction factor for tubes, bends and other pipe connections. A link can be made to the mechanical energy balance.
Week 3: Convection: Mass and Heat transport
- Convective transport is much more powerful than diffusion. It is also much more complex and in most cases can only be treated using (dimensionless) correlations for the transfer coefficients.
- Along with convective heat transfer the analogy is introduced with mass transfer.
Week 4: Mass transfer
- Mass transfer between two phases is introduced. Further the partition coefficient between two phases is explained.
Week 5: Laminar flow
- Definition of Newtonian and non-Newtonian fluids and the derivation of the velocity profile between two parallel flat plates and in a tube.
Week 6: Radiation
- Introduction of the radiation; heat transfer (Stefan-Boltzmann).
- Illustration by its relevance in practice (radiation, emission, transparency, “grey” bodies).

L’université de technologie de Delft (en néerlandais : Technische Universiteit Delft), plus connue sous le nom de TU Delft est la plus ancienne et importante université publique des Pays-Bas.
Elle est implantée à Delft, aux Pays-Bas. Elle est positionnée dans le classement mondial des universités QS en 2022 parmi les 10 premières universités en ingénierie et technologie dans le monde. En architecture et génie civil, elle était classée 2e dans le monde, après le MIT (Massachusetts Institute of Technology)
Платформа
EdX est une plateforme d'apprentissage en ligne (dite FLOT ou MOOC). Elle héberge et met gratuitement à disposition des cours en ligne de niveau universitaire à travers le monde entier. Elle mène également des recherches sur l'apprentissage en ligne et la façon dont les utilisateurs utilisent celle-ci. Elle est à but non lucratif et la plateforme utilise un logiciel open source.
EdX a été fondée par le Massachusetts Institute of Technology et par l'université Harvard en mai 2012. En 2014, environ 50 écoles, associations et organisations internationales offrent ou projettent d'offrir des cours sur EdX. En juillet 2014, elle avait plus de 2,5 millions d'utilisateurs suivant plus de 200 cours en ligne.
Les deux universités américaines qui financent la plateforme ont investi 60 millions USD dans son développement. La plateforme France Université Numérique utilise la technologie openedX, supportée par Google.
