Abstract: High-energy asymmetric heavy-ion interactions generate miniature high-density subatomic interaction volumes that allow researchers to map out the minimal spatial boundaries required to establish liquid-like quark-gluon plasma states. This paper implements a relativistic hydrodynamic modeling framework to simulate multi-particle production cascades and measure elliptic flow fluctuations during asymmetric neon-gold (Ne-Au) collision events. We carried out numerical runs using a 3+1 dimensional viscous hydrodynamic code matched to a statistical hadronization processing module to evaluate final-state momentum metrics. The initial geometric configurations were derived via a Monte Carlo Glauber scheme to capture localized sub-nucleon density fluctuations. The simulations demonstrate that the high-acceleration expansion profile builds a large radial flow signature, boosting the average transverse momentum parameters of emerging kaons up to 1.15 GeV/c in central runs. The simulated elliptic flow index (v²) showcases a clear mass-ordering trend, matching tracking statistics compiled by heavy-ion detectors within a tight ±5.2% accuracy margin. This behavior proves that intermediate asymmetric collision tracks can support brief, fluid-like collective hydrodynamic expansions.
