Energy conditions are validated for the reconstructed model.

Type I-IV singularities are analyzed in the context of the model.

Abstract

In this paper, we have used the reconstructed DBI-essence dark energy density to modify the mass accretions of black holes and wormholes. In general, the black hole mass accretion does not depend on the metric or local Einstein geometry. That is why we have used a generalized mechanism by reconstructing the DBI-essence dark energy reconstruction with f(R) gravity. We have used some particular forms of the scale factor to analyze the accretion phenomena. We have shown the effect of cosmic evolution in the proper time variation of black hole mass accretion. Finally, we have studied the validity of energy conditions and analyzed the type I - IV singularities for our reconstructed model.
