  • Effects of booms of sounding rockets in flowing plasmas 
    Paulsson, Joakim John Paul; Miyake, Y.; Miloch, Wojciech Jacek; Usui, H. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Effects of booms of a sounding rocket on rocket charging and on the local plasma conditions are studied with numerical and analytical models accounting for flowing, ionospheric plasmas. Simulations are carried out with a ...
  • Numerical simulations of a sounding rocket in ionospheric plasma: Effects of magnetic field on the wake formation and rocket potential 
    Darian, Diako; Marholm, Sigvald; Paulsson, Joakim John Paul; Miyake, Y.; Usui, H.; Mortensen, Mikael; Miloch, Wojciech Jacek (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The charging of a sounding rocket in subsonic and supersonic plasma flows with external magnetic field is studied with numerical particle‐in‐cell (PIC) simulations. A weakly magnetized plasma regime is considered that ...
