Transport Phenomena, Basic Course

Valid for: 2014/15

Decided by: Education Board C

Date of Decision: 2014-04-14

Main field: Technology.

Compulsory for: B2, K2

Language of instruction: The course will be given in Swedish

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
- be able to explain how transport of momentum, heat and mass can occur
- be able to identify the rate-determining step and to identify the driving force for the process.

Competences and skills

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.

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
- 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, mixing, mass exchangers, scrubbers
- Simultanous mass and heat transfer: Mollier diagram, wet temperature, air conditioning, cooling tower.

In order to study systems of unit operations three project exercises are included in the course. These collect the applications from the chemical engineering and the bioengineering fields to be studied by Chemical Engineering student and Bioengineering students, respectively.

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.

Grading scale: TH

Assessment: Written examnination as well as project exercises presented in report and participation in laboratory studies.
