### 你将学到什么

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

### 课程概况

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.

### 课程大纲

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.

Introduction of the radiation; heat transfer (Stefan-Boltzmann).
Illustration by its relevance in practice (radiation, emission, transparency, “grey” bodies).

### 预备知识

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
