| dc.description.abstract | Results of numerical studies of a linear Faraday type MHD accelerator using
Quasi-one dimensional computational methods is presented. A working gas of airplasma,
consisting of diatomic molecules
of nitrogen, oxygen and hydrogen, is
considered
in order to actualize application
of the MHD accelerator
propulsion
system.
In order to solve the set of differential
equations of magnetohydro-
dynamics, the MacCormack scheme is employed. Numerical results show the
characteristics of push power, flow velocity, gas temperature and electrical
conductivity of the MHD accelerator with changes for outlet wides. The best
performance of wide channel outlet design computations are compared with
numerical simulation results in past studies.
With this condition resulted 15,7 mm
wide channel outlet made the best performance for propultion effect. Furthermore
by increasing amount of magnetic field strength, push power output for 15,7 mm
gives better value with up to 33,763.83 KW/m

, when around 1.0 – 2.5 Tesla. But
the previous design channel work greatly better on supermagnet influence 3.0 –
4.0 Tesla, with push power up to 196,742 KW/m
