Brief presentation of the institution

KTH Royal Institute of Technology is a university in Stockholm, Sweden, specialized in Engineering and Technology, that ranks highest in northern mainland Europe in its academic fields. Today, KTH is the largest, oldest, and most international recognized technical university in Sweden. The university provides one-third of Sweden's research and engineering education. In 2012, there were a total of 14,000 undergraduate students, 1,700 postgraduate students, and 4,600 members of staff at the university

Main Plasma with liquids related topics

The research within the Department of Electromagnetic Engineering ETK at KTH is focused on three research areas:
  • Theoretical studies on the prebreakdown phenomena in dielectric liquids
  • Characterization of streamer discharges propagating along oil-pressboard interfaces
  • Physical processes of dielectric failure in oil-based nanofluids

 

Main Plasma with liquids related research techniques and equipment

High voltage generators

.- Bipolar square pulse high-voltage generator (risetime 35 ns) up to 30 kV

- Marx generator up to 100 kV

 

Diagnostics of plasmas:

- Differential charge measurement with resolution down to 0.3 pC

- Fast, low current measurement system

- High voltage measurements with corresponding high speed oscilloscope

- Shadow-photography with far field microscope

- Photon counter

Brief information on available facilities related to Plasma with liquids

The research is based on two main reactors:

 

- pulse discharge chamber with a point-plane electrode system including a mechanical system to arrange accurately polymer or cellulose-based films along the streamer path in mineral oil

- pulse discharge chamber with a point-plane electrode system for study of nanofluids and the corresponding associated nanofluid handling equipment
