The current project aims at enabling key technology for patient-specific diagnostics and treatment of Obstructive Sleep Apnea (OSA). When evaluating treatment options, clinicians are currently relying on general guidelines and personal experience, but they are lacking objective and predictive...

Prosjektets målsetting er å legge til rette for og utvikle grunnleggende teknologi for pasientspesifikk diagnostikk og behandling av obstruktiv søvnapne (OSA). Valg av behandlingsstrategi avhenger i dag i stor grad av generelle retningslinjer og behandlerens personlige erfaring. Det mangler...

A cylindrical cooled probe (cold-finger placed in cross-flow) has been used to investigate fouling in the off-gas duct located upstream from the gas cleaning system during primary aluminium production. Hard scale was formed on the front side of the probe whereas loose deposits accumulated on the...

A cylindrical fouling probe or “cold-finger” has been used to investigate fouling from aluminium production off-gas. The probe was located upstream from the off-gas cleaning system. Surface deposits have been collected for further analysis by EPMA and XRD, and compared with off-gas dust and old...

In this paper, investigations are conducted using Reynolds-averaged Navier-Stokes (RANS) turbulence models to investigate the importance of turbulence modelling for nasal inspiration at a constant flow rate of 250 ml/s. Four different, standard turbulence models are tested in a model geometry based...
