Capillary forces as a limiting factor for sawing of ultrathin silicon wafers by diamond multi-wire saw
Ryningen, Birgit; Tetlie, Pål; Johnsen, Sverre Gullikstad; Dalaker, Halvor (Peer reviewed; Journal article, 2020)Succeeding with ultrathin silicon wafer sawing by diamond multi-wire saw, is not only a matter of optimization; the challenges of thin wafer production and the capability limit have not yet been fully understood. In this ... -
Composition and Structure Analysis of Hard Grey Scale (HGS) Formed on Cold Surfaces Exposed to Aluminium Production Off-gas
Perez Clos, Daniel; Zedel, Hannes; Johnsen, Sverre Gullikstad; Nekså, Petter; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2022)Hard grey scale (HGS) is a strongly adhering fouling material forming on solid surfaces impinged by off-gas generated in the pot cells of primary aluminium production plants. Even though associated maintenance costs have ... -
Enabling Efficient Heat Recovery from Aluminium Pot Gas
Clos, Daniel Perez; Andresen, Trond; Nekså, Petter; Johnsen, Sverre Gullikstad; Aune, Ragnhild Elizabeth (The Minerals, Metals & Materials Series;2367-1181, Chapter, 2017) -
Investigation on scale formation in aluminium industry by means of a cold-finger
Clos, Daniel Perez; Nekså, Petter; Johnsen, Sverre Gullikstad; Aune, Ragnhild Elizabeth (Journal article; Peer reviewed, 2019)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 ... -
Particle deposition characteristics in the formation of Hard Grey Scale (HGS) on cold surfaces exposed to aluminium production off-gas
Clos, Daniel Perez; Zedel, Hannes; Johnsen, Sverre Gullikstad; Nekså, Petter; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2021)Hard Grey Scale (HGS) is a hard and strongly adhering fouling material that forms on solid surfaces impinged by the off-gas generated in the pot cells of aluminium production plants. Different theories on HGS formation ... -
Patient Specific Numerical Simulation of Flow in the Human Upper Airways for Assessing the Effect of Nasal Surgery
Jordal, Maria Rolstad; Johnsen, Sverre Gullikstad; Dahl, Sigrid Kaarstad; Müller, Bernhard (SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative ...
