Avdelningen för Strömningslära och Experimentell mekanik har tillsammans med
avdelningen för Material- och Solidmekanik valt att investera i ett gemensamt laboratorium
för avancerad mekanikforskning.
To aid the quality and trust of computer simulations experiments are important. Our laboratory contain advanced equipment for measuring flow, velocities and pressure by various methods.
Röntgenbaserad mikrotomografi används för att göra en fullständig 3D avbildning av ett föremål, utifrån ett visst antal röntgenbilder som tas från olika vinklar.
A laser Doppler Vibrometer (LDV) is a non-contact vibration velocity (or displacement) transducer which uses the Doppler shift of back scattered laser light (He-Ne, of wavelength of 633 nm) from a moving surface.
The versatile laser system can be used in a number of applications. Since the system is injection seeded the two laser cavities are coherent and holographic recordings can be made.
A modern high-speed IR camera system financed by the Kempe Foundations has been purchased. The number of pixels are 320x256 and the sensitivity is around 25mK.
This light source can deliver 2 μs light pulses at 10 kHz frequency or 100 ns light pulses at 200 kHz frequency. The wavelength is 810 nm and the light can be launched in a fibre optic cable and optics to create a suitable illumination spot. The laser is easy to synchronise with a high-speed camera.
