TRANSPORT PHENOMENA, BASIC COURSE | KETF01 |

**Aim**

The aim is to transfer the understanding of molecular processes based on a natural science perspective into an understanding of macroscopic processes. Applications are collected from the fields of chemical engineering, biotechnology and from ecological systems.

*Knowledge and understanding*

For a passing grade the student must

- be able to explain the concepts of force and pressure in hydrostatic systems based on basic physics.
- be able to define the concepts of momentum, heat and mass transfer and to explain how momentum, heat and mass are transferred.
- be able to identify the rate-determining step and to identify the driving force for the process.

*Skills and abilities*

For a passing grade the student must

- be able to apply momentum transfer knowledge on applications within fluid dynamics by solving problems theoretically and practically.
- be able to apply heat transfer knowledge on applications within heat engineering by solving problems theoretically and practically.
- be able to apply mass transfer knowledge by solving problems theoretically.
- be able to apply mass and heat transfer simultaneously on the air-water system by solving problems theoretically.
- be able to present the solution of a problem in a short written communication as an internal company report.
- be able to use advanced calculation programs to solve problems within momentum, heat and mass transfer.

**Contents**

First basic physics is applied to hydrostatics discussing force and pressure. These are used to describe, momentum-, heat-, and mass transfer with applications collected from chemical as well as bio technical systems.

The following fields are covered:

- Momentum transfer: basic fluid mechanics, rheology, dimensional analysis, Navier-Stoke equations, flow in boundary layers, flow around submerged bodies, sedimentation, flow in porous beds, fluidisation
- Heat transfer: basic heat engineering, coefficients for heat transfer, heat exchangers, radiation, instationary heat transfer
- Mass transfer: basic mass transfer calculations, diffusion of gases and liquids, instationary mass transfer, analogies

By solving a number of practical problems the skill to solve engineering problems is trained at the same time as the basic theories are demonstrated.

In two laboratory exercises the ability to work in pilot plant scale is trained.
