In this paper, we have proposed a model of accelerating Universe with binarymixture 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 darkenergy $\omega_{de}$ 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 $H_{0} = 69.80 \pm1.64~km~s^{-1}Mpc^{-1}$ and $70.0258 \pm 1.72~km~s^{-1}Mpc^{-1}$ by restrictingour derived model with recent OHD and joint Pantheon compilation SN Ia data andOHD 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 representsa model of transitioning Universe with transition redshift $z_{t} = 0.7286$. Wehave constrained the present value of jerk parameter as $j_{0} = 0.969 \pm0.0075$ with joint OHD and Pantheon data. From this analysis, we observed thatthe model of the Universe, presented in this paper shows a marginal departurefrom $\Lambda$CDM model.
