  1. 1. Analysis of wall-mounted hot-wire probes

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Alvisi Alex; Perez Adalberto; [2020]
    Nyckelord :Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

    Sammanfattning : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Joar Bagge; [2015]
    Nyckelord :Fluid mechanics; Stokes flow; rigid body dynamics; spheroidal particles; inertia; integral equations; boundary integrals; double layer potentials; quadrature by expansion; Jeffery orbits; linear shear flow; quadratic flow; paraboloidal flow; Strömningsmekanik; Stokesflöde; stelkroppsdynamik; sfäroidiska partiklar; tröghet; integralekvationer; randintegraler; dubbellagerpotentialer; quadrature by expansion; Jeffery-banor; linjärt skjuvflöde; kvadratiskt flöde; paraboloidiskt flöde;

    Sammanfattning : Particle suspensions occur in many situations in nature and industry. In this master’s thesis, the motion of a single rigid spheroidal particle immersed in Stokes flow is studied numerically using a boundary integral method and a new specialized quadrature method known as quadrature by expansion (QBX).

  4. 3. Reactive-Di usive Flow Inside Porous Medium

    Master-uppsats, KTH/Mekanik

    Författare :Peyman Olad; [2015]
    Nyckelord :;

    Sammanfattning : Understanding the reactive-di usive turbulent ow inside porous media is interesting in many applications. It could have geochemical applications such as describing the rock dissolution patterns in river beds or the e ect of riparian zones in nitrate attenuation. Other applications could be, e.g. LÄS MER

  5. 4. A Study of the Twin Fin Concept for Cruise Ship Applications

    Master-uppsats, KTH/Marina system

    Författare :Frida Nyström; [2015]
    Nyckelord :;

    Sammanfattning : The aim with this thesis is to investigate if the Twin Fin concept can be a beneficial propulsion system for large cruise ships, about 300 m long. The Twin Fin concept is a new propulsion system, launched in 2014 by Caterpillar Propulsion [1]. LÄS MER

  7. 5. Investigation in the Simulation of the Human’s Heart Structure from the Mathematical Perspective

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Ebrahim Amani; [2012]
    Nyckelord :Cardiovascular system; Heart function; Mathematical Simulation; Numerical methods; Immersed Boundary Method IMB ; Heart muscles Myocarium ;

    Sammanfattning : The present work has been done after a question defined by the author about the approaches of the human’s heart simulation. In this way, the structure and function of the heart have been investigated to understand the anatomy and physiology of the heart. LÄS MER
