  1. 1. Experimental assessment of fluid hammer prediction algorithms

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Jessica Kihlström; [2018]
    Keywords : ;

    Abstract : Fluid hammer is a problem, which may lead to catastrophic consequences and many engineers have a deficiency in competence when it comes to its prediction. This study´s objective is to assess various fluid hammer prediction models, to evaluate how substantial pressure thrusts would affect a system and to verify the analytical results toward experimental data.

  2. 2. Identification and evaluation of internal leakages of a BFB Boiler integrated within a pulp and paper mill.

    University essay from Högskolan i Gävle/Energisystem

    Author : Adrian Gomez; [2018]
    Keywords : leakages; internal leakages; Pulp and Paper; valves; boiler;

    Abstract : Alternative fuels like biomass have become really popular in the last decades as a substitute to fossil fuels. One of the most used technologies in Sweden for the obtention of the energy from the biomass is its direct combustion in a boiler. READ MORE

  3. 3. Influence of inflow conditions on simulations of arterial blood flow

    University essay from KTH/Mekanik

    Author : Marcus Strimell Flodkvist; [2018]
    Keywords : ;

    Abstract : The blood is responsible for the oxygenation of the body and to carry nutrients to the different parts of the body and waste products away from the major organs like the liver, kidneys but also the walls of the arteries. Blood is composed of red blood cells that are on average 45% of the total volume, the rest of the blood is made up of blood plasma platelets, white blood cells, minerals and nutrients. READ MORE

  4. 4. Performance and model calibration ofhigh-pressure compressors

    University essay from KTH/Energiteknik

    Author : Antoine Brissaud; [2018]
    Keywords : ;

    Abstract : To fully determine the performances of high-pressure compressors (HPC), modeling and partial tests can beperformed to characterize its different operating conditions. Nevertheless, there are still noticeable errorsbetween the results of these models and the tests: deformations and differences can appear, and notably becauseof a modeling defect or the assumptions made during the analysis (measurement corrections for example).

  5. 5. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE
