  1. 1. Advancements in stratified flows through simulation, experiment and open research software development

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Ashwin Vishnu Mohanan; KTH.; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geophysical flows; shallow water wave turbulence; energy cascade; stratified turbulence; waves and vortices; open source software; geofysikaliska strömningar; vågturbulens i grunt vatten; energi- kaskad; stratifierad turbulens; vågor och virvlar; öppen mjukvara; Teknisk mekanik; Engineering Mechanics;

    Abstract : Two studies of two-dimensional models of flows influenced by stratification and stratification/rotation are carried out in order to investigate whether a two-dimensional model can reproduce a downscale energy cascade with an associated k − 5/3 wavenumber spectrum. Firstly, a series of highly resolved numerical simulations of the classical shallow water model is carried out. READ MORE

  2. 2. Stability and transition in pitching wings

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Prabal Negi; KTH.; KTH.; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The aeroelastic stability of airplanes is one of the most important aspects of airplane design. Flutter or divergence instabilities arising out of the interaction of fluid forces and structural elasticity must be avoided by design or through the limitation of the flight envelope. READ MORE

  3. 3. Experimental studies of large particles in Newtonian and non-Newtonian fluids

    University dissertation from KTH Royal Institute of Technology

    Author : Sagar Zade; KTH.; KTH.; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Teknisk mekanik; Engineering Mechanics;

    Abstract : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.

  4. 4. Of Pipes and Bends

    University dissertation from KTH Royal Institute of Technology

    Author : Jacopo Canton; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear instability; bifurcation; flow control; Teknisk mekanik; Engineering Mechanics;

    Abstract : This work is concerned with the transition to turbulence of the flow in bent pipes, but it also includes an analysis of large-scale turbulent structures and their use for flow control.The flow in a toroidal pipe is selected as it represents the common asymptotic limit between spatially developing and helical pipes.

  5. 5. Advances in droplet evaporation

    University dissertation from KTH Royal Institute of Technology

    Author : Giandomenico Lupo; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.
