(Master thesis, 2008)Denne masteroppgaven gikk ut på studere konseptet behovsstyrt ogg behovstilpasset ventilasjon i skolebygg, og gjøre beregninger i den forbindelse. I tillegg ble det gjennomført en spørreundersøkelse. Spørreundersøkelsen ... -
Behovsstyrt ventilasjon i passivhus, lavenergiboliger og blokkbebyggelse
(Master thesis, 2008)Hensikten med oppgaven er å utrede muligheten for bruk av behovsstyrt ventilasjon i lavenergiboliger, passivhus og blokkbebyggelse. Det er sett på energibehovet til lavenergiboliger, forslag til systemløsninger ved ... -
Biodiesel i Trondheim: Biodiesel fra oljeholdig restaurantavfall - En mulighetsstudie
(Master thesis, 2007)Med bakgrunn i de økte problemene med global oppvarming og de store klimagassutslippene fra transportsektoren, har det i det siste blitt rettet søkelys på klimavennlige alternativer for fossile brennstoff. Transportsektoren ... -
Biomass gasification integration in recuperative gas turbine cycles and recuperative fuel cell integrated gas turbine cycles: -
(Master thesis, 2007)A multi-reactor, multi-temperature, waste-heat driven biomass thermochemical converter is proposed and simulated in the process simulation tool Aspen Plus . The thermochemical converter is in Aspen Plus integrated with a ... -
Breakage and coalescence mechanisms in oil/water gravity separators
(Master thesis, 2011)The equipment used for bulk separation operations in offshore activities to produce oil and gas is an important part of the oil and gas production chain. The part of the separation where you separate water from oil is often ... -
Bygningers energiytelse- energiattest
(Master thesis, 2007)Hensikten med masteroppgaven er å energiattestere utvalgte yrkesbygg, som på grunnlag av dette skal sammenlignes. Utfordringer man støter på under arbeidet skal dokumenteres, og eventuelle avvik mellom planlagt og reelt ... -
Cable optimization in a specific Wind Farm
(Master thesis, 2010)Most commonly used wake models were developed in the 80`s, and gave satisfactory results for small WF`s or single turbines. Amongst these models are Ainslie, J.F, Jensen, N.O, and Crespo, A. It has however been agreed that ... -
Calculation of Particle Resuspension Using Static and Dynamic Particle Models
(Master thesis, 2011)The aim of this master work was to investigate particle resuspension from fouled heatexchanger surfaces. In metallurgical industries, the waste gas may contain dust and particles which can deposit on the heat exchanger ... -
Cartesian grid methods for the compressible Navier-Stokes equations
(Master thesis, 2012)A Cartesian grid method has been developed for solving the 2D Euler and Navier-Stokes equations for viscous and inviscid compressible flow, respectively. Both steady and unsteady flows have been considered. Using a simplified ... -
Chemical Looping Combustion Cold Flow Model commissioning and performance evaluation
(Master thesis, 2010)SINTEF and NTNU are planning to build a 150 kWth Chemical Looping Combustion (CLC) reactor system. This is new technology and the CLC reactor system is going to be one of the largest of its kind in the world. The technology ... -
CO2 Capture from Coal fired Power Plants
(Master thesis, 2008)Coal is the most common fossil resource for power production worldwide and generates 40% of the worlds total electricity production. Even though coal is considered a pollutive resource, the great amounts and the increasing ... -
CO2-innfanging ved kraftgenerering: Teknologi for CO2-rensing
(Master thesis, 2007)Avgass fra kraftproduksjon kan inneholde produkter fra brenselet (Hg, H2S, N2, SO2, SO3), fra forbrenningen (H2O, NO, NO2, CO, CH4, O2) og fra oksygentilførselen (N2, Ar). Det er behov for presise termodynamiske modeller ... -
Coal-fired Power Plants based on Oxy-combustion with Carbon Capture: Combustion Conditions and Water Consumption
