  1. 1. Aircraft Winglet Design

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hanlin GongZhang; Eric Axtelius; [2020]
    Keywords : ;

    Abstract : Aerodynamic drag can be decreased with respect to a wing’s geometry, and wingtip devices, so called winglets, play a vital role in wing design. The focus has been laid on studying the lift and drag forces generated by merging various winglet designs with a constrained aircraft wing. READ MORE

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

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

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

    Abstract : 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). READ MORE

  4. 3. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hamidreza Rastan; [2019]
    Keywords : Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Abstract : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  5. 4. Winglet Effect on Induced Drag for a Cessna 172 Wing

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alexander Schumacher; Erik Sjögren; Tobias Persson; [2014]
    Keywords : ;

    Abstract : The perfect wing is a dream that many airplane manufactures have been striving to achieve since the beginning of the airplane. The goals are usually the same for everyone; - Increase lift - Reduce drag - Minimize weight A combination of these goals lead to a decrease in fuel consumption, which in turn reduces pollution in our atmosphere with the added bonus of an increase in economic revenue.
