  1. 1. Tesla Valve for Hydrogen Decompression: Fluid Dynamic Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Elias Bäckman; Mathilda Willén; [2019]
    Keywords : Decompression; Hydrogen gas; Tesla valve; no-moving parts; CFD; valve-to-valve; 压降;氢气;特斯拉阀;无可动阀芯;计算流体动力学;级间距; Decompression; Hydrogen gas; Tesla valve; No-moving parts; CFD; valve-to-valve;

    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE

  2. 2. OPTIMIZATION OF NOZZLE SETTINGS FOR A FIGHTER AIRCRAFT

    University essay from Mälardalens högskola/Industriell ekonomi och organisation; Mälardalens högskola/Industriell ekonomi och organisation

    Author : Alexander Stenebrant; Nor Al-Mosawi; [2019]
    Keywords : Low-bypass turbofan; afterburner; convergent-divergent nozzle; afterbody drag; computational fluid dynamics.;

    Abstract : Most fighters use the convergent-divergent nozzle configuration to accelerate into the supersonic realm. This nozzle configuration greatly increases the thrust potential of the aircraft compared to the simpler convergent nozzle. READ MORE

  3. 3. Case Data Analysis Tool for PowerFLOW

    University essay from KTH/Flygdynamik

    Author : Guillermo Díaz Vázquez; [2019]
    Keywords : ;

    Abstract : The field of computational fluid dynamics (CFD) is exponentially growing in terms of performance, robustness, and applications. The expansion of CFD also means more users and more simulations, which translates into more human errors and mistakes in the simulation set up. READ MORE

  4. 4. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  5. 5. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Erik Edin; Mattias Ström; [2019]
    Keywords : FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Abstract : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. READ MORE
