Accelerating universe with binary mixture of bulk viscous fluid and dark energy

In this paper, we have proposed a model of accelerating universe with binary mixture of bulk viscous fluid and dark energy (DE) and probed the model parameters: present values of Hubble's constant H-0, equation of state paper of DE Omega(de) and density parameter of DE (Omega(de))(0) with recent observational H(z) data (OHD) as well as joint Pantheon compilation of SN Ia data and OHD. Using cosmic chronometric technique, we obtain H-0 = 69.80 +/- 1.64km s(-1)Mpc(-1) and 70.0258 +/- 1.72km s(-1)Mpc(-1) by restricting our derived model with recent OHD and joint Pantheon compilation SN Ia data and OHD, respectively. The present age of the universe in derived model is estimated as t(0) = 13.82 +/- 0.33Gyr. Also, we observe that derived model represents a model of transitioning universe with transition redshift z(t) = 0.7286. We have constrained the present value of jerk parameter as j(0) = 0.969 +/- 0.0075 with joint OHD and Pantheon data. From this analysis, we observed that the model of the universe, presented in this paper, shows a marginal departure from Lambda CDM model.
