Experimental investigation on integrated two-stage evaporators for CO2 heat-pump chillers
(Chapter, 2022)In this experimental study the performance of novel compact evaporator configuration was investigated. What makes this evaporator configuration unique is the integration of a gravity-fed/ self-circulation evaporator loop ... -
Experimental investigation on NOx reduction by primary measures in biomass combustion: straw, peat, sewage sludge, forest residues and wood pellets
(Journal article; Peer reviewed, 2012)An experimental investigation was carried out to study the NOx formation and reduction by primary measures for five types of biomass (straw, peat, sewage sludge, forest residues/Grot, and wood pellets) and their mixtures. ... -
Experimental investigation on the effect off near walls on the eigen frequency of a low specific speed francis runner
(Journal article; Peer reviewed, 2019)The importance to correctly predict the natural frequency of a turbine runner have been demonstrated several times. It is now common practice to include the added mass effect of the surrounding water when calculating the ... -
Experimental investigation on the structural response of RC slabs subjected to combined fire and blast
(Peer reviewed; Journal article, 2021)Reinforced concrete (RC) submerged floating tunnels (SFTs) represent a possible solution for crossing wide, deep fjords, and is considered for the E39 highway route along the Norwegian west coast. With regard to SFTs, the ... -
Experimental Investigationand Numerical Simulation ofThermal Recovery ProcessesApplicable in AthabascaBitumen Reservoirs
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:274, Doctoral thesis, 2013)Due to reduction of high quality oil resources and consequently increase of oil price around the world, new sources of energy should be found to relief the high demand of energy. Hence, countries like Venezuela, United ... -
Experimental Investigations and Modelling of Solid-State Ilmenite Reduction with Hydrogen and Carbon Monoxide
(Doctoral thesis at NTNU;2015:309, Doctoral thesis, 2015)Ilmenite is an important raw material for titanium-containing products. Currently, it is processed using large amounts of coal but this could be substituted with natural gas. This could potentially increase the efficiency ... -
