  1. 1. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    University essay from Lunds universitet/Teknisk geologi

    Author : Simon Kreipl; [2021]
    Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

  2. 2. Pipe Surface Roughness at Microscale and Discussion of Possible Relation to Flow Properties

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Yiting Qiao; Mahsa Kajbaf Nezhad; [2021]
    Keywords : pipe flow; roughness; microscale; SEM; Technology and Engineering;

    Abstract : Despite decades of intense research, the behavior of water molecule still warrants new research.Water flow through various pipe systems has become a pivotal corner stone of functioning human infrastructure. READ MORE

  3. 3. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

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

    Author : Jacqueline Pierri; [2021]
    Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

    Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE

  4. 4. Design and Modelling of a Container for Optimal Flow Rate and Wastewater Purification

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olle Stenlund; [2021]
    Keywords : CFD Simulation; Design; Construction; Pumping System; Water purification;

    Abstract :   Industries are becoming more aware of how they use water in their production process. In many cases, they release wastewater back into the water supply untreated, which can cause adverse side effects to the ecosystem. A sustainable environment requires efficient water purification. One approach to purify wastewater uses rotating bed reactors. READ MORE

  5. 5. Internal strain in the magnetocaloric alloy MnCoSi

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Olivia Vaerst; [2021]
    Keywords : MnCoSi; Magnetocaloric Effect; Arc Melting; Strain; X-Ray Diffraction; Williamson-Hall; Rietveld Refinement; Physics and Astronomy;

    Abstract : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. READ MORE
