  1. 1. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

    Master-uppsats, KTH/Energiteknik

    Författare :Lorenzo Centonze; [2023]
    Nyckelord :;

    Sammanfattning : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

    Sammanfattning : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. LÄS MER

  4. 3. How much can the cross-linking of chromatographic media affect the porosity?

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Carl Östling; [2022]
    Nyckelord :Liquid chromatography; Size exclusion chromatography; Agar; Chromatographic resins; Distribution coefficient; Vätskekromatografi; Storleksuteslutningskromatografi; Agar; Stationär fas; Fördelningskoefficient;

    Sammanfattning : Vätskekromatografi är vanligt förekommande metod för separationer av molekyler inom bioteknik. Det finns inom begreppet vätskekromatografi många olika tekniker och vilken specifik teknik som är mest lämplig för en given separation beror på egenskaperna hos den avsedda målmolekylen. LÄS MER

  5. 4. Carnot Batteries as a Power-to-X-to-Power Alternative : A Study on Optimization of Thermal Energy Storage Usage

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

    Författare :ERIK FORSMAN; [2021]
    Nyckelord :;

    Sammanfattning : The implementation of renewable energy sources continues the rise throughout the world as a means to combat the threats of climate change. This does however bring with it problems within the power sector. LÄS MER

  7. 5. Design and Modelling of a Container for Optimal Flow Rate and Wastewater Purification

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Olle Stenlund; [2021]
    Nyckelord :CFD Simulation; Design; Construction; Pumping System; Water purification;

    Sammanfattning :   Industries are becoming more aware of how they use water in their production process. In many cases, they release wastewater back into the water supply untreated, which can cause adverse side effects to the ecosystem. A sustainable environment requires efficient water purification. One approach to purify wastewater uses rotating bed reactors. LÄS MER
