  1. 16. Analysis of the intake grill for marine jet propulsion

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Söderberg Jansson; [2019]
    Nyckelord :Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

    Sammanfattning : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. LÄS MER

  3. 17. 3D-Printed Heat Exchanger

    Master-uppsats, Lunds universitet/Innovation

    Författare :Johannes Ljungman; [2019]
    Nyckelord :Additive Manufacturing; Heat Transfer; Heat Exchanger; Computational Fluid Dynamics; Computer Aided Design; Technology and Engineering;

    Sammanfattning : Additiv tillverkning, eller 3D-printing, är på grund av sina många fördelar en ständigt ökande tillverkningsmetod. Designfriheten, det reducerade materialspillet, förkortad tid från ritning till färdig produkt och förmågan att kunna printa rörliga delar gör 3D-printing intressant för många olika användningsområden.

  4. 18. CFD analysis of a glider aircraft : Using different RANS solvers and introducing improvements in the design

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :David Perez Sancha; [2019]
    Nyckelord :CFD; RANS; Standard Cirrus; glider; Fluent; SU2; OpenFOAM; SST; transition; winglet.;

    Sammanfattning : In this study, Computational Fluid Dynamics (CFD) simulations have been carried out in order to investigate and improve the performance of the Standard Cirrus glider, using different Navier-Stokes methods and solving the equations for the steady flow. The work has been divided in two parts: First, a study is performed to test the quality of the transition model (Gamma-ReTheta). LÄS MER

  5. 19. CFD Analysis of Heat Transfer in an Innovative Facade System

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Christoffer Bågholt; [2018]
    Nyckelord :Computational Fluid Mechanics; Heat Transfer; Building Physics;

    Sammanfattning : New innovative façade systems that are well thought out, rational, sustainable and energy efficient are needed for renovation of old buildings to drastically reduce the heat losses through walls and to improve indoor conditions. In order to achieve the above mentioned goal, new innovative modular systems that can be mounted on site with ease are an interesting alternative. LÄS MER

  7. 20. CFD analysis of stepped planing vessels

    Master-uppsats, KTH/Mekanik

    Författare :Toni Kokkonen; [2018]
    Nyckelord :Computational Fluid Dynamics CFD ; Ship hydrodynamics; Planing hull; Stepped hull; STAR-CCM ; Overset mesh; Volume of fluid VOF ; Reynolds averaged Navier-Stokes equations RANS ; Dynamic instabilities;

    Sammanfattning : High speed planing hulls are currently widely used for example in recreational and emergency vessel applications. However, very little CFD research has been done for planing vessels, especially for those with stepped hulls. A validated CFD method for planing stepped hulls could be a valuable improvement for the design phase of such hulls. LÄS MER
