DIFFUSION ASSOCIATED NEOCLASSICAL INDEGINOUS SYSTEM OF HALL ASSEMBLY(DANISHA) FOR HALL EFFECT THRUSTER AND SUPPRESSION OF FLR & SHEAREDAXIAL FLOW ON RTI

A.B.R.HAZARIKA

DEPT. OF MATHEMATICS, DIPHU GOVT. COLLEGE, DIPHU, ASSAM, INDIA-782462 e-mail: [email protected] [email protected] [email protected] ABSTRACT Suppression of sheared axial flow and finite larmor radius (FLR) on Rayleigh-Taylor instability with

Diffusion associated neoclassical indigenous system of Hall assembly (DANISHA) is studied in

toroidal geometry coordinates for derived magneto hydrodynamic formulation for getting the thrusteffect by using such magnetic device used for first time .The DANISHA hall thruster works for22000(twenty two thousand hours) instead of 8000 hrs in case of SPT-100. The sheared axial flowis introduced into MHD and FLR effect via. The sheared axial flow with a lower peak velocitysuppresses the RT instability. It is observed that the FLR suppress the RT instability strongly thanthe sheared axial flow. The results are same as in case of slab geometry.

Keywords: Z-pinch implosions, rayleigh-taylor instability, finite larmor radius, sheared axial flow,MHD formulation, plasma propulsion, Hall thruster, plasma bridge, Hall effect devices, Hall effecthybrid, Magnetic device for propulsion.
