A CFD analysis for the performance assessment of a novel design of plates-in-tank latent storage unit for freezing applications
Selvnes, Håkon; Allouche, Yosr; Sevault, Alexis; Hafner, Armin (Chapter, 2019)In this paper, the charging and discharging processes of a recently developed cold thermal energy storage (CTES) unit integrated into a poultry processing plant is investigated. A mathematical model of the CTES was created ... -
A novel PCM accumulator for refrigerated display cabinet : design and CFD simulations
Sevault, Alexis; Banasiak, Krzysztof; Bakken, Jørn; Hafner, Armin (Chapter, 2018) -
CFD modeling of ice formation and melting in horizontally cooled and heated plates
Selvnes, Håkon; Allouche, Yosr; Sevault, Alexis; Hafner, Armin (Chapter, 2019)This paper investigates the ice formation and melting processes in a novel CTES unit using the commercial CFD software ANSYS Fluent 19. The storage unit is designed to operate as a peak shaving device integrated into the ... -
Cold thermal energy storage with low-temperature plate freezing of fish on offshore vessels
Verpe, Espen Halvorsen; Tolstorebrov, Ignat; Sevault, Alexis; Hafner, Armin; Ladam, Yves (Chapter, 2019)This paper presents the results of a numerical and experimental study of freezing time for fish in plate freezers, and the potential for improvement by altering fish block thickness and lowering evaporation temperature. ... -
Design av en PCM-basert varmelagrinsenhet for ZEB Flexible Laboratory
Bøhmer, Fabian (Master thesis, 2019) -
Experimental design and testing of a PCM-based heat storage unit for wood stoves
Mathisen, Henning Hvål (Master thesis, 2019)Bruken av vedovner har lange tradisjoner i Norge, både når det gjelder oppvarming og hygge. Moderne hus er gjerne godt isolerte med lite varmetap og siden vedovner typisk har høy varmeavgivelse, kan dette føre til overoppheting ... -
Investigation of an Innovative Latent Heat Storage Concept in a Stovepipe
Sevault, Alexis; Soibam, Jerol; Haugen, Nils Erland L; Skreiberg, Øyvind (Journal article; Peer reviewed, 2018)Latent heat storage (LHS) is a promising concept for small-scale batch combustion. One example is wood stoves, which rely on a batch combustion process that yields a transient heat production with high peak effect. A ... -
Investigation of the structure of oxy-fuel flames using Raman laser diagnostics
Sevault, Alexis (Doktoravhandlinger ved NTNU, 1503-8181; 2012:166, Doctoral thesis, 2012) -
Investigation of Turbulent Oxy-Fuel Jet Flames Using Raman/Rayleigh Laser Diagnostics
Sevault, Alexis; Barlow, R.S.; Dunn, M.; Ditaranto, Mario (Others, 2011) -
Latent heat storage for centralized heating system in a ZEB living laboratory: integration and design
Sevault, Alexis; Bøhmer, Fabian; Næss, Erling; Wang, Liang (Journal article; Peer reviewed, 2019)The ZEB Lab project, coordinated by SINTEF and NTNU, aims at building a ZEB (Zero Emission Building) in Trondheim (Norway) in 2019, to be used both as office building and living laboratory. An innovative latent heat storage ... -
On the structure of the near field of oxy-fuel jet flames using Raman/Rayleigh laser diagnostics
Sevault, Alexis; Dunn, Matthew; Barlow, Robert S.; Ditaranto, Mario (Journal article; Peer reviewed, 2012)An experimental study on turbulent non-premixed jet flames is presented with focus on CO2-diluted oxy-fuel combustion using a coflow burner. Measurements of local temperatures and concentrations of the main species CO2, ... -
Phase change materials for thermal energy storage in low- and high-temperature applications: a state-of-the-art
Sevault, Alexis; Kauko, Hanne; Bugge, Mette; Banasiak, Krzysztof; Haugen, Nils Erland L; Skreiberg, Øyvind (Research report, 2017) -
Study of CO2 gasification reactivity of biocarbon produced at different conditions
Wang, Liang; Maziarka, Przemysław; Skreiberg, Øyvind; Løvås, Terese; Wadrzyk, Mariusz; Sevault, Alexis (Journal article; Peer reviewed, 2017)Biocarbon has a great potential to replace fossil reductants and help reduce greenhouse gas emissions from carbon intensive metallurgical industries. In this work, biocarbon samples were produced from Norway spruce under ...
