  1. 21. Design of a radial-inflow microturbine for combined heat and power generation unit

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Salvador María Beltrán Martínez; [2021]
    Nyckelord :radial inflow turbine; turbomachinery; rotor; nozzle vanes; reaction; design; TurbAero; CAD; blade speed ratio; specific speed; efficiency; turbine exhaust; turbine; inlet; pressure drop; Euler equation; losses; blade loading plot; pressure side; suction side; Technology and Engineering;

    Sammanfattning : This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.. LÄS MER

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mayur Khedekar; [2021]
    Nyckelord :ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

    Sammanfattning : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. LÄS MER

  4. 23. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Framtidens energi

    Författare :Emil Skoglund; [2021]
    Nyckelord :PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

    Sammanfattning : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. LÄS MER

  5. 24. Reverse analysis of the epoxy kinetic model : A search for kamal model parameters to fit measured data

    Kandidat-uppsats,

    Författare :Oday Asalya; Joar Fjällborg; Lucas Hagert; [2021]
    Nyckelord :;

    Sammanfattning : This report is about the curing of epoxy and how to find a model to fit the measured temperature data. The curing process of the polymer was modeled using Kamal model, which includes several parameters. LÄS MER
