In this study, we present a novel approach to modeling cosmic expansion using interacting vortices governed by fluid mechanics. By calibrating our simulation to physical units, we compare the resulting Hubble constant with two independent observational determinations: one from early-universe (Planck) data and the other from local measurements (SH0ES) . The vortex model yields results in close agreement with both values, demonstrating its robustness. This work highlights fluid dynamics as a viable analog framework for exploring cosmological phenomena.
