  1. 1. 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

  2. 2. CFD and Experimental Study of Refuelling and Venting a Fuel System

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära;

    Author : Aditya Naronikar; Anton Riström; [2019]
    Keywords : CFD; VOF; multiphase; refuelling; gasoline; ORVR; automotive; volvo;

    Abstract : In 1999, California Air Resources Board (CARB) implemented a regulation that required all gasoline cars sold in California be fitted with an Onboard Refueling Vapor Recovery System (ORVR). The ORVR system is designed to prevent Volatile Organic Compounds (VOCs) from escaping into the atmosphere during refuelling by storing the gas vapours in a carbon canister. READ MORE

  3. 3. Mekanismer hos tillväxtfrämjande antibiotika

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Miranda Blad; [2019]
    Keywords : tillväxtfrämjande; antibiotika; produktionsdjur;

    Abstract : Antibiotika har använts inom djurproduktion i tillväxtfrämjande syfte sedan den effekten uppdagades för över 50 år sedan. Med en ökande resistensproblematik har dock användningen ifrågasatts och i stora delar av världen även förbjudits. READ MORE

    Keywords : CFD; refuelling; automotive; ORVR; fuel; VOF; volume of fluid; multiphase;

    Abstract : In 1999, California Air Resources Board (CARB) implemented a regulation that required all gasoline cars sold in California be fitted with an Onboard Refueling Vapor Recovery System (ORVR). The ORVR system is designed to prevent Volatile Organic Compounds (VOCs) from escaping into the atmosphere during refuelling by storing the gas vapours in a carbon canister. READ MORE

  5. 5. Evaluation of GM trees expressing a fungal enzyme : investigating the effects of the fungal enzyme on activation of jasmonate signaling using JAZ10:GUS reporter lines of Arabidopsis

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Elin Bäckström; Therese Thalin; [2019]
    Keywords : cell wall formation; cell wall composition; genetic modification; genetic improvement; ; GUS;

    Abstract : The fungi enzyme glucuronoyl esterase can be used to change the cell wall composition in plants for easier extraction of cellulosic biomass compounds for the production of biomaterials and biofuels. However, previous studies have shown that expression of glucuronoyl esterase in plants causes stress response, mediated by jasmonate signaling, and growth penalty. READ MORE
