  1. 1. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
    Keywords : Urea; AdBlue; SCR; Solid Deposit; NOx; nitrogen oxides; CFD; speedup; spray simulation; UWS; diesel after-treatment; STAR-CCM ; AVL Fire; Scania; Sweden; NXPS; LiU; DOE; Urea; AdBlue; SCR; Klump; NOx; kvävedioxider CFD; uppsnabbning; spray simulering; UWS; efterbehandling av diesel-motor; STAR-CCM ; AVL Fire; Scania; Sverige; NXPS; LiU; DOE;

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE

  2. 2. Software Benchmark and Material Selection in an Exhaust Manifold : Thermo-mechanical fatigue simulation of an exhaust manifold in AVL Fire M

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Oskar Rombo; [2018]
    Keywords : thermomechanical fatigue; TMF; simulation; viscoplastic;

    Abstract : Today, there is a great focus on downsizing the engines, this means that the engines are made smaller in size but retain the same power. This in combination with the drive to increase the power of the engines has led to the engine components being exposed to high thermal loads. Today’s engines also use very high cylinder pressure.

  3. 3. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

    University essay from KTH/Mekanik

    Author : Emelie Trigell; [2018]
    Keywords : after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

    Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE

  4. 4. Simulation and validation of in-cylinder combustion for a heavy-duty Otto gas engine using 3D-CFD technique

    University essay from KTH/Förbränningsmotorteknik

    Author : Jacob Arimboor Chinnan; [2018]
    Keywords : CFD; AVL FIRE; Otto Gas Engine; Combustion Modelling; ECFM Model; Flame Tracking Particle Model; Flame Tracking Model; G-Equation Model; Ignition Models.; CFD; AVL FIRE; Otto Gasmotor; Förbränningsmodellering; ECFM-modell; Flamspårningspartikelmodell; Flamspårningsmodell; G-ekvationsmodell; Tändningsmodeller;

    Abstract : Utsläpp från bilar har spelat stor roll de senaste decennierna. Detta har lett till ökad användning av Otto gasmotorer som använder naturgas som bränsle. Nya motordesigner behöver optimeras för att förbättra motorens effektivitet. READ MORE

  5. 5. Material choice for a rotor in a switched reluctance high speed motor

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christoffer Christiansen; [2017]
    Keywords : SRM; switched reluctance motor; Electrical Steel; Materials;

    Abstract : With the increasing environmental impact from the automotive industry, electric vehicles become more and more popular. This combined with the great breakthroughs in fast electronics the switched reluctance motor (SRM) has again gained popularity in recent years. READ MORE
