| Popis | We prove a robustness of regularity result for the 3D convective Brinkman-Forchheimer equations partial derivative(t)u - mu Delta u + (u . del) u + del p + alpha u + beta vertical bar u vertical bar(r-1) u = f, for the range of the absorption exponent r is an element of[1, 3] (for r > 3 there exist global-in-time regular solutions), i.e. we show that strong solutions of these equations remain strong under small enough changes of the initial condition and forcing function. We provide a smallness condition which is similar to the robustness conditions given for the 3D incompressible Navier-Stokes equations by Chernyshenko et al. [5] and Dashti & Robinson [8]. |
