About

I am from Os, a small town close to Bergen in Norway. I graduated the summer 2004 from the Department of Electronics and Telecommunications, NTNU in Trondheim, Norway. The last year of my degree I was exchange student here at the Applied Acoustic, Chalmers, where I also wrote the master thesis. The theme of the thesis was about the design of a microphone array technique for localizing sources in a wind tunnel.

I started as PhD student here at Applied Acoustic in September 2004. So now I am doing research in the thermoacoustic field, especially looking closer at thermoacoustic refrigerators and the possibility to optimise it with active control.

Beyond that I am playing the tuba, and enjoy cayak, concerts and good food.

Research projects

The potential to optimise thermoacoustic devices by means of active control of the acoustic field

Financed by Swedish Research Council

Objectives

The main objective of the proposed project is to investigate the potential for improving the performance of thermoacoustic devices when actively controlling the acoustic field.

Scope of the work

The scope of the work is to find a model for thermoacoustic devices in the time domain, make simulations of thermoacoustic devices and optimise the performance with active control. All the simulations will be validated by experiments.

  • Simulation and experimental validation of model for a thermoacoustic device.
  • Extension of model to include varying boundary conditions, developing of cost function and control algorithm.
  • Optimisation of thermoacoustic devices by active control.
