A simple method of supersonic plasma jet production where the jet is formed in a cylindrical channel guiding the plasma generated from a laser-irradiated thin foil target is proposed and examined. High-Mach number (≥10) plasma jets of parameters relevant to laboratory astrophysics applications using 120 J, 1.315 μm, and 0.3 ns laser pulse for a thin CH foil irradiation are demonstrated. The method seems to be flexible in the production of jets of various compositions and hydrodynamic parameters and does not require high-energy lasers for the jet generation.

    We present experimental results on the formation of supersonic, radiatively cooled jets driven by pressure due to the toroidal magnetic field generated by the 1.5 MA, 250 ns current from the MAGPIE generator. The morphology of the jet produced in the experiments is relevant to astrophysical jet...

    The mixing characteristics of a Mach 1.6 axisymmetric jet in the presence of two Mach 2.5 axisymmetric jets canted away from the center jet axis has been investigated experimentally. It is found that, in the presence of surrounding jets the central (core) jet decays faster and there is a large...

    In this paper the transition from convective to absolute instability in a reacting compressible mixing layer with finite rate chemistry is examined. The reaction is assumed to be one step, irreversible, and of Arrhenius type. It is shown that absolute instability can exist for moderate heat...
