  1. 1. Optimization of Cavity Receiver Geometry with regards to Radiation Heat Loss

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Simon Ottosson; Fredrik Wahlgren; [2016]
    Nyckelord :Cavity receiver; CSP; Radiation heat loss;

    Sammanfattning : In order to maximize the e ciency of power generation in concentrated solar power systems (CSP) it is de- sired to achieve as high a tempera- ture in the receiver as possible due to the use of the Sterling cycle to gen- erate power. This report investigates three di↵erent geometries for cavity receivers in CSP systems; cylindrical, conical and truncated conical. LÄS MER

  3. 2. Numerical study of surface heat transfer enhancement in an impinging solar receiver

    Master-uppsats, Uppsala universitet/Fasta tillståndets fysik

    Författare :Lifeng Li; [2014]
    Nyckelord :Jet impingement; Computational fluid dynamics CFD ; Conjugate heat transfer; Ribbed surface; Solar receiver;

    Sammanfattning : During the impinging heat transfer, a jet of working fluid, either gas or liquid, will besprayed onto the heat transfer surface. Due to the high turbulence of the fluid, the heat transfer coefficient between the wall and the fluid will be largely enhanced. LÄS MER

  4. 3. Numerical Study on the Thermal Performance of a Novel Impinging Type Solar Receiver for Solar Dish-Brayton System

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Haoxin Xu; [2013]
    Nyckelord :Solar receiver; Jet impingement; Conjugate heat transfer; Computational fluid dynamics;

    Sammanfattning : An impinging type solar receiver has been designed for potential applications in a future Brayton Solar Dish System. The EuroDish system is employed as the collector, and an externally fired micro gas turbine (EFMGT) has been chosen as the power conversion unit. LÄS MER
