  1. 1. Spatial Decompositions of a Fully-developed Turbulent Round Jet Sampled with Particle Image Velocimetry

    Författare :Maja Wänström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; proper orthogonal decomposition; axisymmetric turbulent jet; PIV; spatial spectral analysis; equilibrium similarity;

    Sammanfattning : Spatial decompositions of the turbulence in a far, axisymmetric jet at exit Reynolds number of 20, 000 have been performed. Equilibrium similaritytheory applied to the two-point Reynolds stresses has shown that the turbulence statistics in the far, fully developed region of an axisymmetric jet should be independent of origin in the streamwise direction when evaluated on the similarity coordinates system.

  3. 2. Antivirulent and antibiofilm salicylidene acylhydrazide complexes in solution and at interfaces

    Författare :Shoghik Hakobyan; Madeleine Ramstedt; Jean-Francois Boily; Mikael Elofsson; Marcus Textor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antivirulent; Antibiofilm; Hydrazones; Gallium; Pseudomonas aeruginosa; Type three secretion system; Equilibrium constant; Chemical equilibrium modelling; Spectrophotometric titration; UV-Vis;

    Sammanfattning : The growing bacterial resistance against antibiotics creates a limitation for using traditional antibiotics and requests development of new approaches for treatment of bacterial infections. Among the bacterial infections that are most difficult to treat, biofilm-associated infections are one of the most hazardous. LÄS MER

  4. 3. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures

    Författare :Rafael Gamero; Joaquín Martínez; Evangelos Tsotsas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary; conduction; convection; diffusion; evaporation; heat transfer; hydraulic conductivity; liquid film; liquid transport; mass transfer; Maxwell-Stefan diffusion coefficients; molar fluxes; phase equilibrium; temperature gradient; ternary mixture; thermodynamic factors; Chemical engineering; Kemiteknik;

    Sammanfattning : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures.  It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity.

  5. 4. Essays on Growth Econometrics and Endogenous Information

    Författare :Tobias Heinrich; John Hassler; José Vicente Rodríguez Mora; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Distinguishability; Observational equivalence; Cointegration; Similarity-Based Expectation Formation; Case-Based Decision Theory; Information Gathering; Discrimination; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : On Testing the Relationship between Human Capital and Economic Growth This paper investigates existing methodologies for testing the so-called Nelson-Phelps approach versus the Lucas approach. The paper shows that one cannot distinguish between these approaches using the existing methodologies. LÄS MER

  7. 5. The Axisymmetric Turbulent Wake

    Författare :Peter Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents a theoretical and experimental study of the turbulent axisymmetric wake. In the theoretical part, an equilibrium similarity solution of the far wake was derived that was found to admit to two different solutions for this flow. LÄS MER
