  1. 1. Prediction of Cooling Air Flow in Electric Generators

    Author : Pirooz Moradnia; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

    Abstract : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. READ MORE

  4. 4. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes

    University dissertation from Stockholm : KTH

    Author : Wahib Owhaib; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minichannel; microchannel; heat transfer; pressure drop; single-phase; two-phase; flow boiling; flow visualization; dry out; bubble behavior; flow pattern.; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Abstract : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. READ MORE

  5. 5. Predicting flow-generated noise from HVAC components

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Oscar Kårekull; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow noise; noise prediction; HVAC; flödesalstrat ljud; bullerprediktion; HVAC;

    Abstract : More energy efficient fans, i.e. larger sizes running at lower speeds, in Heating Ventilation and Air Conditioning (HVAC) systems decrease the fan noise and increase the importance of flow generated noise in other system components, e.g. READ MORE
