The Field Laboratory

Published: 21 August 2012

The division of Fluid and Experimental mechanics has together with the division of Mechanics of Solid Materials invested in a common laboratory for advanced research within mechanics.

Background to The John Field Laboratory

A common strategy has resulted in the following objectives to be achieved within two years.

LTU has one of Europe's leading and well-functioning laboratory for advanced measurements of flow and deformation and several concepts for making measurements in the field. We use and are constantly developing new methods for laboratory and field.

We are now working to realize that goal. The area measurement techniques for studies of mechanical phenomena is now developing rapidly. New photonic components makes it possible to measure phenomenon at a resolution and accuracy that previously were not possible while accelerating computer development enables the storage and processing of large amounts of data in short time. This means that we can study the complex processes in intricate shapes, something that was previously impossible. Advances in mechanical field also means that interest in advanced measurements increases. Among other things, in order to validate numerical models, but also to produce data on which calculations do not work at all or to study new phenomena. Advanced measurement technologies will additionally together with on-line simulations increasingly be used for process control.

The name of the John Field Laboratory aimed at LTU's honorary doctor Professor John Field at the Cavendish Laboratories in Cambridge which recurrent have spent a few weeks a year at Luleå University for over thirty years.

Current status

At TVM is currently a large arsenal externally funded and internally developed measurement instruments for measuring mechanical phenomena. Examples of equipment include:

  • Particle image velocimetry
  • Micro particle image velocimetry
  • Laser Doppler anemometry
  • Laser Doppler vibrometry
  • Image Correlation
  • Stereoscopic image correlation
  • Holographic methods
  • Pulsed laser systems
  • High-speed cameras
  • Thermal camera
  • Mikroröntgentomograf.

Current departments, mainly the subject Experimental Mechanics, also develop their own unique measurement equipment. The equipment is mainly used for measurements in the laboratory but also in the field and contribute to publishable results and results useful for society and industry. Moreover, they are an important element in our advanced courses. There are also additional equipment on other subjects at the institution such as Machine Elements and Energy Technology. The grouping can therefor be seen as leading in Sweden regarding advanced measurements of flow and deformation. We have also hired a research engineer with the task of coordinating and ensuring the availability of the lab. The aim is to allow for other subjects at the university and externally to station some of their experimental research in this lab.

Investments

Below is a list of equipment we primarily have chosen to focus on in the coming year.

  • Purchase of Laser Doppler velocimeter.
  • Upgrading the PIV system.
  • Upgrade of micro-PIV system.
  • Purchase of Double cavity OPO.
  • Upgrade of micro-xray tomograph.
  • Upgrading the Laser Doppler Vibrometer.
  • Purchase of high-speed camera:
