  In the cores of dense stellar clusters, close gravitational encounters
between binary and single stars can frequently occur. Using the Tsunami code,
we computed the outcome of a large number of binary-single interactions
involving two black holes (BHs) and a star to check how the inclusion of
orbital energy losses due to tidal dissipation can change the outcome of these
chaotic interactions. Each interaction was first simulated without any
dissipative processes and then we systematically added orbital energy losses
due to gravitational wave emission (using post-Newtonian (PN) corrections) and
dynamical tides and recomputed the interactions. We find that the inclusion of
tides increases the number of BH-star mergers by up to 75 per cent but it does
not affect the number of BH-BH mergers. These results highlight the importance
of including orbital energy dissipation due to dynamical tides during few-body
encounters and evolution of close binary systems within stellar cluster
simulations. Consistent with previous studies, we find that the inclusion of PN
terms increases the number of BH-BH mergers during binary-single encounters.
However, BH-star mergers are largely unaffected by the inclusion of these
terms.
