Abstract

Modern space programs set specialized practical problems to the developers while designing new engines and their upgrading.

Capillary pulse discharge with an evaporating wall of the channel was described in [1].

As a part of the radiating plasma dynamics, taking into consideration the radiation transfer, the problem is set as follows: plasma and gas-dynamic processes in the flame of a capillary discharge with an electrode vaporizing under the assumption that the brightness temperature and the temperature of the outflowing plasma are equal to each other. The results of calculations are given in [1].

Numerical studies of pulsejet, flowing through rather «wide» slice, the channels of more than three millimeters, revealed that the jet formed unsteady vortex structures near the boundaries.

It presents the spatial distribution of temperature and pressure of the jet, formed by three channels, for times: t = 18.5 ms, t = 41.6 ms, t = 94.6 s.

The impact of the magnetic field is considered. For a single channel capillary discharge with an evaporating electrode it demostrates the distributions of temperature in the flame of a capillary discharge when applied to a stream of the external magnetic field B = 1.58 Tl and B = 2.5 Tl, respectively.

The magnetic field affects the high temperature (near the axis) of the plasma jet and a wake vortex (toroidal vortex) in a triple configuration of the shock waves.

If the value of the magnetic pressure p_mag= 25 atm, toroidal vortex
does not occur, and the longitudinal size of jet is approximately twice the
size of the jet without a magnetic field presence. Similarly, the maximum value
of the temperature obtained is 1.5–2 times greater than the temperature value obtained
by the calculation without the effect of the external magnetic field.
