  2. 1. Experimental investigation of flows related to gas turbine combustion

    Author : Dragan Stankovic; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

  4. 2. A Particle Image Velocimetry Study of Bubbly Gas-Liquid Flow

    Author : Xiaoyun Tu; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent dispersion; Food and drink technology; Livsmedelsteknik; turbulence; Rushton turbine; stirred tank; slip velocity; bubbly gas liquid two-phase flow; coherent structure; CCD camera; PIV; POD;

    Abstract : The aim of this work is to build a framework that can be used for characterizing the bubbly gas liquid turbulent flow in the stirred bioreactor tank. To this end we have developed and modified techniques with which to measure the velocity of both dispersed gas and carrier liquid phases by the optical measurement technique, a 2-CCD camera Particle Image Velocimetry (PIV) system; and to characterize the turbulence by the wavelets tool, Proper Orthogonal Decomposition (POD).

  5. 3. An experimental study of the flow in a sharp-heel Kaplan draft tube

    Author : Urban Andersson; Torbjørn K Nilsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : This research project was originally part of a package (Turbine-99 Draft Tube) that had a mutual goal, to improve the understanding of draft tube flow and establish Best Practise Guidelines for simulation of draft tube flow.The draft tube is situated after the runner in a Hydropower turbine to recover as much of the remaining head and kinetic energy as possible before the water leaves the turbine.
