Gradient-based design optimization and off-design performance prediction of Rankine cycles and Radial Inflow Turbines
Hagen, Brede Andre Larsen (Doctoral theses at NTNU;2022:147, Doctoral thesis, 2022)A major fraction of today's electricity is generated by Rankine cycle power systems utilizing the thermal energy of fossil sources such as coal and natural gas, or nuclear energy. However, the carbon content in the fossil ... -
Heat transfer and pressure drop of supercritical CO2 in brazed plate heat exchangers of the tri-partite gas cooler
Zendehboudi, Alireza; Ye, Zuliang; Hafner, Armin; Andresen, Trond; Skaugen, Geir (Peer reviewed; Journal article, 2021)The heat transfer characteristic of supercritical CO2 is an essential research topic due to its significant influence on the performance of heat exchangers and systems. In this paper, the heat transfer and pressure drop ... -
Heat-to-power conversion from variable surplus heat sources utilizing a thermal energy storage

Interaction Between a Building Complex with an Integrated Thermal Energy System and a District Heating System
Rohde, Daniel; Andresen, Trond; Nord, Natasa (Chapter, 2016)Integrated thermal energy systems provide heating and cooling for several commercial and residential buildings. These systems usually have both short-term and seasonal thermal energy storages. High cooling demands lead to ... -
Introduction of a Parallel Electronic Currency in a Eurocrisis Country - Modelling and Simulation of Transient Economic Dynamics
Granbakken, Thea Allum (Master thesis, 2021)Denne avhandlingen utvikler en modell for sannsynlig dynamikk ved en introduksjonsprosess av en parallell elektronisk valuta i et eurokriseland. Modelldynamikken baserer seg på et forslag kalt Electronic Parallel Money ... -
Is a Job Guarantee program a viable economic solution during a pandemic? A modelling approach
Trømborg, Torjus (Master thesis, 2021)Økende arbeidsledighet er et globalt problem. Å gå arbeidsledig over lengre tid kan ha negative sosiale og økonomiske konsekvenser. Et Jobbgaranti-program kan være en løsning på verdens arbeidsledighetproblem. Jobbgaranti ... -
Mathematical modeling of CO2 based heat pumping systems: New developments for simulation tools to aid the design of systems for non-residential buildings
Andresen, Trond (Doktoravhandlinger ved NTNU, 1503-8181; 2009:180, Doctoral thesis, 2009)CO2 based heat pumping systems have in recent years received considerable focus world-wide. Now, attention has been turned toward heating and cooling of larger, non-residential buildings. With plate heat exchanger’s now ... -
Modeling and Simulation of Human Folly in Decision Making Processes
Torseth, Hege Hjelen (Master thesis, 2015)This master's thesis is about modelling and simulation of "human folly" in decision making processes. What makes us humans act incorrect when we deep down know what is the right thing to do? The answer to this question is ... -
Modeling, Simulation and Control of Short-term Stock Market Dynamics
Pedersen, Henning (Master thesis, 2009)Real-world stock markets exhibit periods of increased volatility and bursts in stock prices. This thesis is about creating similar dynamics in a model to gain insight into these potentially dangerous phenomena. A transaction ... -
Modellering og simulering av aksjemarkeds-dynamikk
Vu, Quoc Vuong Hoang (Master thesis, 2017)I denne rapporten er det gjort modifisering og simuleringer av modellen for et kortsiktig aksjemarked til Trond Andresen. I modellen er det inkludert to typer handels mentalitet, det fundamentale og spekulative. Spekulativ ... -
Modellering og simulering av samfunnsøkonomi med arbeidsløshet kontra et system med "jobbgaranti"
Flatgård, Anders (Master thesis, 2013)Dette prosjektet omhandler modellering av 2 dynamiske modeller, hvor resultatene fra disse modellene er sammenlignet. Den ene modellen er laget for å kunne simulere et samfunn med bruk av jobbgaranti (JG) og moderne ... -
Modelling and simulation of an Economy with "Basic Income" or "Job Guarantee"
Kragh, Ida Margrethe (Master thesis, 2016)In this report there has been designed a dynamic model of a country's economy using a stock-flow approach. The economy is hit by a great export crisis when the price of the country's main export product drops rapidly. As ... -
Modelling and simulation of CO2 (carbon dioxide) bottoming cycles for offshore oil and gas installations at design and off-design conditions
Walnum, Harald Taxt; Nekså, Petter; Nord, Lars Olof; Andresen, Trond (Peer reviewed; Journal article, 2013)Improved energy efficiency is an issue of increasing importance in offshore oil and gas installations. The power on offshore installations is generated by gas turbines operating in a simple cycle. There is an obvious ... -
Modelling and simulation of parallel monetary systems for countries without their own currency
Lund, Håkon Teigen (Master thesis, 2017)Greece is one of the countries still struggling after the financial crisis in 2008. With a debt burden of almost the double the gross domestic product, they are in a situation where repaying the debt can seem nearly ... -
Modelling, simulation and control of macro economic systems.
