By means of 3-D hydrodynamical simulations, here we evaluate the impact thatsupernova explosions occurring within wind-driven bubbles have on the survivalor destruction of dust grains. We consider both, the dust generated within theejecta and the dust initially present in the ambient gas and later locked-up inthe surrounding wind-driven shell. The collision of the supernova blast wavewith the wind-driven shell leads to a transmitted shock that moves into theshell and a reflected shock into the ejecta. The transmitted shock is capableof destroying large amounts of the dust locked in the shell, but only if themass of the wind-driven shell is small, less than a few tens the ejected mass.Conversely, massive wind-driven shells, with several times the ejected mass,lead upon the interaction to strong radiative cooling, which inhibits theSedov-Taylor phase and weakens the transmitted shock, making it unable totraverse the wind-driven shell. In such a case, the destruction/disruption ofthe ambient dust is largely inhibited. On the other hand, the SNRs grow rapidlyin the very tenuous region excavated by the stellar winds, and thus a largefraction of the dust generated within the ejecta is not efficiently destroyedby the supernova reverse shock, nor by the reflected shock. Our calculationsfavor a scenario in which core-collapse supernovae within sufficiently massivewind-driven shells supply more dust to the ISM than what they are able todestroy.
