  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fawzi Kayali; [2023]
    Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

  3. 2. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Namika Maharjan; [2023]
    Keywords : Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Abstract : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. READ MORE

  4. 3. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

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

    Author : LINDA YANG; [2023]
    Keywords : Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

    Abstract : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. READ MORE

  5. 4. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  6. 5. Evaluation of Cyber-Attacks in Networked Control Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Teja Kedar Vadde Hulgesh; [2023]
    Keywords : ;

    Abstract : Networked Control Systems (NCS) form an essential role in numerous critical infrastructures, including water distribution plants, water treatment plants, electric power grids, and power transmission networks. NCS employ a communication network to share data between the plant and the controller.
