  1. 6. Rankine Cycles, Modeling and Control

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ylva Teleman; [2016]
    Nyckelord :dynamic; modeling; organic rankine cycles; Modelica; simulation; Dymola.; Rankine cycles; Technology and Engineering;

    Sammanfattning : As the demand for decreased use of energy increases, new ways of using energy sources are investigated. One of these ways is to be able to use low temperature heat sources, which can be done with a rankine or organic rankine cycle. LÄS MER

    Nyckelord :ORC; Waste Heat Recovery; Aspen Plus; Cascaded Cycle; Thermo-Economic; ORC Simulations; ORC Models; ORC Model Comparisons; Gas Engine Waste Heat Recovery; Hot Exhaust Gases; Multiple Waste Heat Sources; ORC Waste Heat Power Generation; Heat and Power; Combined Cycle; Siloxane;

    Sammanfattning : Increasing the efficiency of conventional power plants is a crucial aspect in the quest of reducing the energy consumption of the world and to having sustainable energy systems in the future. Thus, within the scope of this thesis the possible efficiency improvements for the Wärtsilä 18V50DF model gas engine based combine power generation options are investigated by recovering waste heat of the engine via Organic Rankine cycle (ORC).

  5. 9. Performance and size assessment of ORCs in mobile military power generation

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Kristina Eriksson; Henrik Persson; [2015]
    Nyckelord :;

    Sammanfattning : In this study the suitability of small-scale organic Rankine cycles in military power generation is evaluated. It is presupposed that external combustion engines have favorable characteristics in terms of noise, heat and vibration signals. LÄS MER

  7. 10. Comprehensive Analysis of Organic Rankine Cycles for Waste heat recovery applications in Gas Turbines and IC Engines

    Master-uppsats, KTH/Elkraftteknik

    Författare :Alejandro Tristan; [2014]
    Nyckelord :;

    Sammanfattning : Executive Summary This investigation aimed to assess the true technical and environmental potential, plus economic feasibility of the ORC technology as bottoming cycles for Gas turbines and IC Engines power applications. The assessment started by creating a modeling tool using the software EES in order to model several bottoming cycle configurations and match them with the mentioned power generation technologies.
