  1. 1. Design & optimization of modular tanksystems for vehicle wash facilities

    Master-uppsats, Karlstads universitet

    Författare :Pontus Marco; [2020]
    Nyckelord :Water reclamation system; Water treatment; Washing system; Modular; Tank system; Fluid flow; Microsoft Excel; Visual Basic for Applications;

    Sammanfattning : Clean and safe water is important for the well being of all organisms on earth. Therefore, it is important to reduce harmful emissions from industrial processes that use water in different ways. In vehicle washing processes, water is used in high-pressure processes, as a medium for detergents, and for rinsing of vehicles. LÄS MER

  3. 2. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.

    Master-uppsats, Mälardalens högskola/Framtidens energi

    Författare :Yash Khanna; [2019]
    Nyckelord :Hybrid electric aircraft system; Thermal management system; micro channel; Dynamic modelling; Mobil Jet Oil II;

    Sammanfattning : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.

  4. 3. Determining the viscous splash losses in the housing of a hydraulic motor through CFD-simulations : A master thesis in collaboration with Bosch-Rexroth in Mellansel AB

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Tommy Larsson; [2017]
    Nyckelord :CFD computational fluid dynamics splash losses efficiency;

    Sammanfattning : One possible way of solving future energy shortages is by the optimization of our current energy consumption. These optimizations must span all possible fields of consumption. In the mechanical field radial piston hydraulic motors may show some margin of improvement. LÄS MER

  5. 4. Hållbara alternativ inom sjöfarten : En utvärdering av metanol och vågkraft som marina drivmedel

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Nevin Gürsoy; Ivan Khudur; [2015]
    Nyckelord :Maritime traffic; wave power; methanol; fuels; emissions; heavy fluid oil; Sjöfart; vågkraft; metanol; drivmedel; emissioner; tjockolja;

    Sammanfattning : Förbränning av traditionellt fartygsbränsle medför utsläpp av ämnen som har negativa effekter på miljön. Uppkomsten av strängare internationella regler gällande utsläpp från sjöfartstrafiken kräver ett skifte från det konventionella marina bränslet tjockolja till alternativ med lägre utsläpp. LÄS MER
