General Information

Main field: Technology.
Compulsory for: B2, K2
Language of instruction: The course will be given in Swedish

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.

Learning outcomes

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 use advanced calculation programs to solve problems within momentum, heat and mass transfer.

Contents

The course present fundamental momentum-, heat-, and mass transfer and applications from chemical and biotechnical systems.

The following fields are covered:

• Momentum transfer: basic fluid mechanics, rheology, pipe and pump systems, flow in boundary layers, flow around submerged bodies, sedimentation
• Heat transfer: basic heat engineering,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 project exercises are included in the course.
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.
