  In this work we explore an alternative phenomenological model to Chaplygin
gas proposed by H. Hova et. al., consisting on a modification of a perfect
fluid, to explain the dynamics of dark matter and dark energy at cosmological
scales immerse in a flat or curved universe. Adopting properties similar to a
Chaplygin gas, the proposed model is a mixture of dark matter and dark energy
components parameterized by only one free parameter denoted as $\mu$. We focus
on contrasting this model with the most recent cosmological observations of
Type Ia Supernovae and Hubble parameter measurements. Our joint analysis yields
a value $\mu = 0.843^{+0.014}_{-0.015}\,$ ($0.822^{+0.022}_{-0.024}$) for a
flat (curved) universe. Furthermore, with these constraints we also estimate
the deceleration parameter today $q_0=-0.67 \pm 0.02\,(-0.51\pm 0.07)$, the
acceleration-deceleration transition redshift $z_t=0.57\pm 0.04\, (0.50 \pm
0.06)$, and the universe age $t_A = 13.108^{+0.270}_{-0.260}\,\times
(12.314^{+0.590}_{-0.430})\,$Gyrs. We also report a best value of $\Omega_k =
0.183^{+0.073}_{-0.079}$ consistent at $3\sigma$ with the one reported by
Planck Collaboration. Our analysis confirm the results by Hova et al, this
Chaplygin gas-like is a plausible alternative to explain the nature of the dark
sector of the universe.
