SUMMARY:Plume Modeling of a CAMILA Hall Thruster Cluster
DESCRIPTION:Lecturer:Matteo Laterza\n Faculty:Department of Aerospace Engin
 eering\n Institute:Technion – Israel Institute of Technology\n Location:
 Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstrac
 t: \n Details: \n The present work focuses on plume interactions in a conv
 ergent Hall thruster cluster for thrust vectoring. The analysis is done th
 rough a numerical model\, using a custom hybrid- PIC code with Monte Carlo
  Collisions for ion-neutral interactions. The setup consists in two thrust
 ers positioned at 10cm separation\, each with a 10° convergence angle. In
  order to provide thrust vectoring\, the ion current is changed by  ±20% 
 relatively to nominal.\nA combined simulation is compared with stand-alone
  simulations of the two thrusters.\nThe comparison shows not only the defl
 ection of high-angle charge-exchange ions\, but also deviations of the mai
 n plume. A non-axisymmetric divergence model is developed\, showing total 
 divergence on the convergence plane to be smaller than single thruster div
 ergence\, contrary to what would be expected.
