30 credits – Electrostatic dust precipitator in automotive application i Sodertalje

Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:
Scania is aiming to build an efficient and low-resistant air cleaning system. However, in classic applications a high air cleaning efficiency causes high pressure drop and vice-versa. So-called “dust electrostatic precipitator” appears to have a huge potential providing an outstanding cleaning efficiency together with minimum of stream energy losses. For better understanding of how this device should be designed there arose a need of investigation the electrostatic means of dust separation.

Target:
The thesis should answer three questions:

• Can we use an electrostatic precipitator on-a truck?
• How high cleaning efficiency can we reach and how much of electric energy is needed for that
• Can we get rid of air filter by substituting it with electrostatic precipitator. If yes, how much fuel can we save in that way.

Assignment:
Thesis will be divided in two parts. The first part is to carry out a thorough study of electrostatic phenomenon, to provide calculations on magnetic field and if possible calculate a necessary geometrical parameters in order to fit it on truck.
The second part is to make a parametric CAD model which can be used further on in electrostatic simulation. It should be robust and flexible within a limited design space and have a link to the air filter dimensions.
