  1. 11. Numerical and experimental study of the fluid flow in porous medium in charging process of stratified thermal storage tank

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Anders Berg; [2013]
    Keywords : heat storage; thermal storage; storage tank; stratified; stratification; porous media; värmelagring; porösa medier;

    Abstract : In order to increase the efficiency of an adsorption heat pump system, a stratified thermal heat storage can be used to enable regeneration of heat between the different phases of the process. It’s crucial to avoid mixing and to keep layers intact inside the storage tank. READ MORE

    Keywords : ;

    Abstract : There is a renewed interest in the wind estimate over and around forest areas dueto the increasing demand of wind-energy resources. Many researches have been donewith simplied forest models. READ MORE

  4. 13. Investigation of wind potential variation at three measurement sites based on atmospheric stability and power production

    University essay from KTH/Kraft- och värmeteknologi

    Author : Lavan Kumar Eppanapelli; [2013]
    Keywords : AQ500; SoDAR; Met mast; statistical analysis; atmospheric stability; wind shear;

    Abstract : As tapping energy from wind expands rapidly worldwide, it is a common procedure to locate a practicable site to extract energy from abundant wind flow by building wind farms. Comprehensive understanding of wind resource at a site   is important to perform the main activities say, wind flow modeling, wind   turbines micro siting, annual energy yield calculation and cost of energy   estimation.

  5. 14. Wake Measurements Behind An Array Of Two Model Wind Turbines

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jan Bartl; [2011]
    Keywords : Wind turbine; wake; wind farm; wake interaction; velocity deficit; turbulence;

    Abstract : During the last decades the exploitation of energy from the wind has become one of the most promising renewable energy technologies. The main strive in today’s development of wind turbines is to increase the efficiency of the turbine and to build bigger rotors that are able to extract more power out of the wind. READ MORE

  6. 15. Modeling of Subcooled Nucleate Boiling with OpenFOAM

    University essay from KTH/Reaktorteknologi

    Author : Edouard Michta; [2011]
    Keywords : ;

    Abstract : Within the course of this master thesis project, subcooled nucleate boiling in a vertical pipe has been modeled using CFD. The modeling has been carried out within the OpenFOAM framework and a two-phase Eulerian approach has been chosen. The code can be used to predict the distribution of the local ow parameters, i.e. READ MORE
