Assessment of heating and cooling demands of a glass greenhouse in Bucharest, Romania
Brækken, August; Sannan, Sigurd; Jerca, Ionut Ovidiu; Bädulescu, Liliana (Peer reviewed; Journal article, 2023)In southern parts of Europe, a balanced use of both heating and cooling is required to control the greenhouse temperatures throughout the year. Especially, with climate change and increasingly hot summers, the need for ... -
A CFD Study of the Fluid Flow through Air Distribution Hoses in a Greenhouse
Sannan, Sigurd; Jerca, Ionut Ovidiu; Bädulescu, Liliana (Peer reviewed; Journal article, 2023)The indoor climate of a greenhouse provides the plants with favorable growing conditions that can result in faster growth and higher yields. Important parameters to control in a greenhouse are the temperature, the humidity, ... -
The CO2 Reduction Potential of Using Black Pellets for Energy Production in Romania
Birgen, Cansu; Sannan, Sigurd (Peer reviewed; Journal article, 2024)In this study, a contextual analysis of the CO2 reduction potential by using black pellets for energy production in Romania was performed. Black pellets have similar fuel properties to that of coal, thus representing a ... -
A Comprehensive Assessment of the Morphological Development of Inflorescence, Yield Potential, and Growth Attributes of Summer-Grown, Greenhouse Cherry Tomatoes
Jerca, Ionuț Ovidiu; Cîmpeanu, Sorin Mihai; Teodorescu, Răzvan Ionuț; Drăghici, Elena Maria; Nițu, Oana Alina; Sannan, Sigurd; Arshad, Adnan (Peer reviewed; Journal article, 2024)Understanding how cherry tomatoes respond to variations in greenhouse microclimate is crucial for optimizing tomato production in a controlled environment. The present study delves into the intricate relationship between ... -
Dimensional Decomposition of Turbulent Reacting Flows
Grøvdal, Fredrik; Sannan, Sigurd; Meraner, Christoph; Li, Tian; Løvås, Terese (Peer reviewed; Journal article, 2020)A dimensional-decomposition approach, decomposing 3D into 3×1D for turbulent (reacting) flows are motivated, discussed and investigated. In the three-dimensional Linear Eddy Model (LEM3D), three orthogonally intersecting ... -

Integrated technologies based on heat pumps, thermal energy storage and smart control systems
Brækken, August; Sannan, Sigurd (SINTEF Rapport;, Research report, 2023)An overview of integrated technologies based on heat pumps, thermal energy storage and smart control systems is provided. Heat pumps are devices that transfer thermal energy from low-temperature to high-temperature areas, ... -
Numerical Simulation of Differential Molecular Diffusion Effects in a Hydrogen-rich Turbulent Jet Using LEM3D
Sannan, Sigurd; Kerstein, Alan R (Peer reviewed; Journal article, 2014)The LEM3D stochastic model for numerical simulation of turbulent mixing is used to simulate differential molecular diffusion effects in an isothermal jet of hydrogen and Freon 22 issued into air. The computations are ... -
Physio-chemical properties of two cherry tomato varieties in relation to the greenhouse environmental factors
Frangulea, Mihai; Bädulescu, Liliana; Jerca, Ionut Ovidiu; Dräghici, Elena Maria; Bantle, Michael; Sannan, Sigurd; Brækken, August; Cimpeanu, Sorin Mihai (Peer reviewed; Journal article, 2022)To prevail on the agricultural market, greenhouse grown cherry tomatoes need to meet certain quality standards. The quality can be assessed by determining several chemical and physical characteristics. The aim of the ... -
Potential for Saccharina latissima Flour as a Functional Ingredient in the Baking Sector
Oprea, Oana Bianca; Tolstorebrov, Ignat; Claussen, Ingrid Camilla; Sannan, Sigurd; Apostol, Livia; Mosoiu, Claudia; Gaceu, Liviu (Peer reviewed; Journal article, 2023)The healthy “superfood” sector is currently quickly developing in Europe, and grocery stores are increasingly stocking macroalgae food supplements. Due to its high amount of protein, fiber, and minerals, numerous studies ... -
