  1. 1. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

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

    Author : Sateesh Nataraj; [2021]
    Keywords : Asperity contact pressure; elastohydrodynamic lubrication; friction; flow factors; run-in wear profile; Asperitetskontakttryck; elastohydrodynamik; friktion; flödesfaktorer; slitageprofil efter inkörning;

    Abstract : Journal bearings are being used in various locations of an internal combustion engine. They contribute to a large portion of total engine friction and lowering it means a significant contribution to CO2 reduction. READ MORE

  3. 2. Parallelization of a thermal elastohydrodynamic lubricated contacts simulation using OpenMP

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

  5. 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

  6. 5. Elastohydrodynamic lubrication in spur gear and helical gear contacts

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Sudeendra Chitta; [2012]
    Keywords : Gears; lubrication;

    Abstract : The gears in a transmission are lubricated to prevent their premature failure as a result of pitting and wear on the tooth surfaces. Furthermore, the lubricant also limits the rise in surface temperature of the gears, which could otherwise lead to failure as a result of scuffing. READ MORE
