  1. 26. Efficiency Analysis of a Wave Energy Converter Penstock

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

    Author : Péter László Bondár; Felix Myrsten; [2021]
    Keywords : Efficiency Analysis; Machine Design; Optimisation; Penstock; Wave Energy Converter; Effektivitetsanalys; Maskinkonstruktion; Optimering; Tilloppstub; Vågkraftverk;

    Abstract : Novige develops a wave energy converter (WEC) concept that utilizes wind-generated wave to create electricity. The system uses a float and a hydraulic cylinder to pump water up to a turbine, similar to an inverted hydro power plant. READ MORE

  3. 27. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Fabian Maletzke; [2021]
    Keywords : turbine; blade cooling; matrix cooling; latticework cooling; CFD; heat transfer; RANS;

    Abstract : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. READ MORE

  4. 28. Effectiveness of using Organic Rankine cycle engine in small-scale district heating systems

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Sarah Ebhuomhan; [2021]
    Keywords : ;

    Abstract : Co-production of electricity and heat using biomass is important in providing sustainable energy for the future. District heating systems, which are well established in Sweden, provide a great opportunity to co-produce electricity simultaneously. READ MORE

  5. 29. Comparison of control strategies for Peltonturbines in Wave Energy Converters

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

    Author : PHILIP HAMILTON; ANDREAS SJÖGREN; [2021]
    Keywords : Permanent Magnet Synchronous Generator; Synchronous Motor; Wave Energy Converter; Pelton Turbine; Velocity Control Strategies; Dead-time Strategies; Cascaded Control; Permanentmagnetgenerator; Synkrongenerator; Synkronmotor; Vågenergiomvandlare; Peltonturbin; Hastighetskontrollstrategier; Mellantidsstrategier; Kaskadreglering;

    Abstract : Wave energy is a promising renewable resource with a higher energy density than both wind and solar. Waves can travel thousands of kilometers with minimal energy loss, making them more reliable than the previously mentioned alternatives. A device that utilizes wave energy to generate electricity is calleda Wave Energy Converter. READ MORE

  6. 30. Do feed-in tariffs promote environmental efficiency among wind farms? : a two-stage LCA + DEA efficiency case study on 75 Danish wind farms

    University essay from SLU/Dept. of Economics

    Author : Gustav Berglöf; [2020]
    Keywords : DEA; efficiency; environmental efficiency; feed-in tariff; operational efficiency; renewable energy; subsidy; wind power;

    Abstract : It is generally known that wind power has an offsetting effect on emissions by crowding out fossil dependent energy sources. What has not been studied to any further extent is the variability in environmental impacts caused by wind turbine erection and manufacturing. Also, it is not known how economic incentives could affect these impacts. READ MORE
