  1. 1. Numerical Modelling of Gas Atomised Metal Droplets

    University essay from KTH/Materialvetenskap

    Author : Nandakishor Thamarassery Illam Muraleedhara Sharma; [2021]
    Keywords : ;

    Abstract : The ability to predict nucleation and solidification behaviour is essential for producing high-quality  metal  powders. The  droplet  cooling  of  complex multi-component  alloy systems has not been accurately  studied  by  any models  to  date. READ MORE

  3. 2. Performance comparison between reciprocating and scroll compressor heat pumps with R600a refrigerant

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : CHRISTOFER KRONSTRÖM; [2021]
    Keywords : Heat pump; R600a; isobutane; scroll compressor; reciprocating compressor; piston compressor; Värmepump; R600a; isobutan; scrollkompressor; kolvkompressor;

    Abstract : A performance comparison of heat pumps using a scroll (Sanden) and a reciprocating (Bitzer) compressor was conducted experimentally. The refrigerant used was R600a (isobutane). READ MORE

  4. 3. 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

    University essay from KTH/Energiteknik

    Author : JiaCheng Lin; HaoRan Teng; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Evaluation of CO2 Ice rink heat recovery system performance

    University essay from KTH/Energiteknik

    Author : Sotirios Thanasoulas; [2018]
    Keywords : Ice rinks; CO2 as refrigerant; Heat recovery; Efficient systems; Operation control; Warm climate; Isrinkar; Koldioxid som kylmedel; Värmeåtervinning; Effektiva system; Driftstyrning; Varmt klimat;

    Abstract : Ice rinks are the largest energy consumers in terms of public buildings due to their simultaneous need of cooling, heating, ventilation, and lighting for different parts of the building which means that these facilities also have a lot of potential for energy saving. Due to the size of the cooling unit in an ice rink the refrigerant charge can become quite high, which potentially has a big impact on the environment. READ MORE
