  1. 1. Hydrological modelling of a recycling facility and landfill

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mazen Tawfik; [2022]
    Keywords : Parsimonious approach; Lumped modelling; Surface water; Landfill; Leachate water; Storage reservoirs.; Technology and Engineering;

    Abstract : A parsimonious lumped model for simulating a catchment composed of a landfill and recycling facility were developed. The modelling results showed an acceptable conformity with the observed values with NSE of 0.54 and R2 of 0.56 in hourly simulations, though the results were characterized by a general underestimation.

  3. 2. Making grid capacity available through heat pump control

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Karin Arding; Siri In de Betou; [2019]
    Keywords : Grid; capacity; electricity; Uppsala; IKEA; peak shaving; electric bus; bus depot; lumped capacity model; Region Uppsala;

    Abstract : In this report the problem of constructing a bus depot with electrical buses despite the lack of grid capacity, was analyzed. A potential solution is investigated, namely smart control of heat pumps in industries. READ MORE

  4. 3. Modelling of Heat Transfer for Convection-boosted Flat Vertical Radiator Surfaces : An investigation of how heat transfer is influenced by radiator height and freestream air velocity

    University essay from KTH/Strömnings- och klimatteknik

    Author : Oskar Scheibe; [2017]
    Keywords : Heat transfer; flat vertical plate; non-isothermal; temperature profile; radiator; energy efficiency;

    Abstract : In this thesis, a calculation model is created to study a theoretical radiator-like configuration, consisting of a flat vertical plate heated with a constant capacity rate. This lumped capacitance model is partly created to more theoretically look at radiators with add-on-fans, but also to in such a setting look at fundamental heat transfer relationships. READ MORE

  5. 4. Using a lumped conceptual hydrological model for five different catchments in Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Madeleine Ekenberg; [2016]
    Keywords : ;

    Abstract : Hydrological models offer powerful tools for understanding and predicting. In this thesis we havereviewed the advantages and disadvantages of physically based distributed hydrological models andconceptually lumped hydrological models. READ MORE

  6. 5. Optimization of Solar Energy to foster the Evaporative Crystallization Process at Lake Katwe, Uganda

    University essay from Akademin för teknik och miljö

    Author : Joseph Ddumba Lwanyaga; [2013]
    Keywords : Solar; Salt; Crystallisation.Evaporation;

    Abstract : Lake Katwe located in Kasese district, is an explosion crater in western rift valley and is the largest of the eight explosion crater lakes in the Katwe-Kikorongo volcanic field, containing a renewable source of natural mineral salts. Salt is produced for 6 months of the year during the dry seasons. READ MORE
