  The high-multiplicity events of pPb collisions at $\sqrt s_{NN}$ = 5.02 TeV
at the LHC exhibit unforeseen collective behaviour. One of the possible
explanations to the collectivity could be the formation of thermalized partonic
matter, like the one formed in relativistic nucleus-nucleus collisions and is
described by the hydrodynamic models. This article presents a study on the
centrality dependent long-range 2 < $|\Delta\eta|$ < 4 two-particle azimuthal
correlations of D-mesons and charged particles in pPb collisions at $\sqrt
s_{NN}$ = 5.02 TeV. The study has been conducted on the events, generated with
the EPOS3 hydrodynamic code that reproduces most of the features of the pPb
data at the LHC energy. There appears a ridge-like structure in the long-range
two-particle angular correlations of D-mesons, in the intermediate pT -range,
and charged particles in the simulated high-multiplicity pPb events.
