Abstract
This study investigates the hydrodynamic expansion of dense plasmas influenced by relativistic degenerate electrons using a quantum hydrodynamic model and self-similarity method. In this research, dimensionless dynamic equations were derived, and the impact of the relativistic parameter on plasma density, velocity, electric potential, and electric field was analyzed. The results show that an increase in the relativistic parameter leads to the expansion of the plasma edge, enhanced density stability, and improved ion expansion velocity. Furthermore, relativistic degeneracy pressure strengthens the electric potential and improves the overall dynamics of plasma expansion. These findings highlight the critical role of degeneracy pressure and relativistic effects in dense plasmas and their significance for industrial and astrophysical applications, including particle accelerators, nuclear fusion, and the analysis of relativistic jets. The proposed analysis provides a new analytical tool for understanding the behavior of dense plasmas in laboratory and astrophysical conditions, paving the way for the development of advanced plasma-related technologies.
