Analysis of a vertical flat heat pipe using potassium working fluid and a wick of compressed nickel foam
Hansen, Geir; Næss, Erling; Kristjansson, Kolbeinn Jakob (Journal article; Peer reviewed, 2016)Heat at high temperatures, in this work 400–650 °C, can be recovered by use of cooling panels/heat pipes in the walls of aluminum electrolysis cells. For this application a flat vertical heat pipe for heat transfer from a ... -
Dampening of wood batch combustion heat release using a phase change material heat storage: Material selection and heat storage property optimization
Kristjansson, Kolbeinn Jakob; Næss, Erling; Skreiberg, Øyvind (Journal article; Peer reviewed, 2016)The use of wood stoves for space heating in energy effective residential buildings can be problematic due to the batch combustion giving a highly transient heat production and the limited regulation of the combustion ... -
Utvikling av et hybrid varmerør for høytemperatur anvendelser
Kristjansson, Kolbeinn Jakob (Master thesis, 2011)Det første målet med denne masteroppgaven er å utvikle en prosedyre for å vakuumere, fylle og forsegle et varmerør (heat pipe). Varmerør benyttes for å transportere varme med lave temperaturdifferanser. Ved høye temperaturer ...
