Robustness of 3D Navier–Stokes System with Increasing Damping

The principal objective of the paper is study three-dimensional Navier–Stokes system with non-autonomous perturbation force term and increasing damping term, which often appears in fluid within saturated porous media other complex media. With some suitable assumptions on parameters external based known result global well-posedness, existence pullback attractors educed, robustness shown via upper semicontinuity as parameter approaches a certain value.
