  1. 1. Cropping systems with leys : analysis of a long-term experiment in Northern Sweden

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Elin Lindén; [2021]
    Nyckelord :yield; yield stability; crop rotation; cropping systems; ley; barley; long-term experiments;

    Sammanfattning : Climate change affects agriculture all over the world and in the Northern hemisphere the change towards warmer temperatures is more rapid than other parts on the planet. As this progresses the need to produce food in a sustainable way and stabilize or increase yields is essential. LÄS MER

  3. 2. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

    Master-uppsats, KTH/Energiteknik

    Författare :JiaCheng Lin; HaoRan Teng; [2019]
    Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

  5. 4. Numerical Analysis ofLatent Thermal Energy Storage in a Cavity

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Robert Olrog; [2017]
    Nyckelord :;

    Sammanfattning : Latent Thermal Energy Storage (LTES) has drawn attention because the technology is a simple and cost-efficient method to store large amounts of energy. Latent energy is either stored or released when the material inside the LTES undergoes phase-change. LÄS MER

  7. 5. Numerical Analysis of Latent Thermal EnergyStorage in Coaxial Component

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Hampus Nilsson; [2017]
    Nyckelord :;

    Sammanfattning : Latent Thermal Energy Storage, LTES, is a system for storing energy for later use. It isused in applications such as buildings, electronics and space shuttles. The problem associatedwith the system is the relatively low charging and discharging power i.e. LÄS MER
