In this paper, we have proposed a model of accelerating Universe with binary mixture of bulk viscous fluid and dark energy. and probed the model parameters: present values of Hubble's constant $H_{ 0}$, Equation of state paper of dark energy $\omega_{ de}$ and density parameter of dark energy $(\Omega_{ de})_{ 0}$ with recent OHD as well as joint Pantheon compilation of SN Ia data and OHD. Using cosmic chronometric technique, we obtain $H_{ 0} = 69.80 \pm 1.64~km~s^{ -1}Mpc^{ -1}$ and $70.0258 \pm 1.72~km~s^{ -1}Mpc^{ -1}$ by restricting our derived model with recent OHD and joint Pantheon compilation SN Ia data and OHD respectively. The age of the Universe in derived model is estimated as $t_{ 0} = 13.82 \pm 0.33\; Gyrs$. 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 $j_{ 0} = 0.969 \pm 0.0075$ 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.
