    Abstract : Transient analyses at Forsmark nuclear power plant are currently performed using realistic computer models in conjunction with conservative estimates of initial- and boundary conditions. This is known as the combined methodology. READ MORE

  4. 3. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

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

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE
