Pump turbines in existing powerplants
(Master thesis, 2019)En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden ... -
Pump-Turbines in Conventional Hydropower Plants
(Peer reviewed; Journal article, 2021)This paper proposes an innovative approach to retrofit existing hydropower plants with suitable upper and lower reservoirs into pumped storage. The conventional methods are both comprehensive and expensive, mainly due to ... -
Pumpe-og effektkraftverk i Nordfjord
(Master thesis, 2012)Den nordiske kraftmarknaden er i endring, mellom anna som følgje av utbygging av mykje uregulert produksjon i Noreg og Europa. Uregulert produksjon må balanserast, og Noreg har reguleringsmagasin som kan nyttast til formålet. ... -
Pumped Storage Development in Øvre Otra, Norway
(Master thesis, 2012)The objective with this thesis was to describe the challenges related to PSH, both for this particular study and in more general terms.The method used was to make assumptions that would apply to traditional hydropower and ... -
Pumpekraftverk for effektproduksjon
(Master thesis, 2008)Europa har et stadig økende energiforbruk, og har samtidig mål om å redusere bruken av fossile brensel. De termiske kraftverkene er trege å regulere, og et økende innslag av vindkraft forsterker en allerede vanskelig ... -
PUMPEKRAFTVERK MELLOM STORE UREVATNET OG VATNDALSVATNET I ØVRE OTRA - TUNNELSYSTEM
(Master thesis, 2012)EU har planer for en storstilt utbygging av uregulerbar kraft, og etterspør regulerbar kraft som kan balansere forskjellen mellom kraftforbruk og kraftproduksjon. Norge har et fleksibelt vannkraftsystem, og kan bli en ... -
Pumpemodul for brannslukkingssystem
(Bachelor thesis, 2020)I denne rapporten har det blitt skapt en pumpemodul for ett nytt brannslukkingssystem. Målet med oppgaven var å lage en modul som kan redde liv og materiell bedre enn dagens sprinkleranlegg. Gjennom krav om strømningshastighet ... -
Pumpesump med integrert forankring
(Bachelor thesis, 2019)Avløpspumpestasjoner brukes for å transportere avløps- og spillvann fra husholdninger, industri og annen virksomhet til avløpsrenseanlegg. Her blir avløpsvannet renset før vannet slippes tilbake til naturen. Pumpesumpen, ... -
Pumpesystem for undervannsbrønner
(Master thesis, 2011)Nowadays,electrical submersible pumping(ESP) is becoming more attractive among artificial lifting methods.The purpose of the submersible pumping is to increase bottom hole pressure. Development of ESPsystems, which are ... -
Pumping iron and manganese: Geochemistry and engineering of groundwater well systems with challenging redox conditions
(Doctoral theses at NTNU;2023:58, Doctoral thesis, 2023)Wells facilitate extraction and injection of groundwater, both for heating/cooling and drinking water purposes. Their ability to supply groundwater of sufficient quantity and quality may be impeded with time. To a large ... -
Pumping of concrete and Mortar - State of the art
(COIN Project report;5-2008, Research report, 2008)The pumpability of concrete, or its ability to move through pipes and hoses by the help of a pump while maintaining its fresh and hardened properties, can be quantified as being better the lower the necessary pressure to ... -
Punctuality development and delay explanation factors on Norwegian railways in the period 2005–2014
(Peer reviewed; Journal article, 2021)The paper revisits an investigation of delays and punctuality on Norwegian railroads from 2010, re-evaluating its findings and studying the effects of later measures put in place between 2010 and 2014. Norwegian railways ... -
Pure Mode I Fracture Toughness Determination in Rocks Using a Pseudo‑Compact Tension (pCT) Test Approach
(Journal article, 2020)Mode I fracture toughness (KIC) quantifies the ability of a material to withstand crack initiation and propagation due to tensile loads. The International Society for Rock Mechanics (ISRM) has proposed four suggested methods ... -
Purification of High-grade Calcite Ore by Flotation with Alkyl Diamines
(Peer reviewed; Journal article, 2018)A very high-grade calcite deposit located in northern Norway consists of CaCO3 ore with minor silicate and sulphide impurities. Cationic (Tallow-1,3-diaminopropane, Duomeen T) collector has been used in the purification ... -
Pushing the limits of beam-steering lens arrays
(Journal article; Peer reviewed, 2019)An essential part of a concentrated solar power system is the solar tracker. Tracking is usually implemented by rotating the entire optical system to follow the sun, adding to the bulk and complexity of the system. ... -
The Puzzle of Project Transaction Costs - Optimising project transaction costs through client-contractor collaboration
(Doctoral theses at NTNU;2021:5, Doctoral thesis, 2021)Kostnadsoverskridelser er et gjentakende problem i bygg- og anleggsnæringen, både nasjonalt og internasjonalt. Totalkostnad i et prosjekt er summen av prosjektets produksjons- og transaksjonskostnader. Med produksjonskostnader ... -
