Fully discrete approximation of a velocity and temperature tracking problem for the Boussinesq equations with piecewise distributed controls

In this article, we study the dynamics of a fully discrete piecewise optimal distributed control problem for the Boussinesq equations which models a velocity tracking over time coupled to thermal dynamics. We prove that the rates of velocity and‐ temperature tracking are exponential. We also give some computational results which reinforces the theoretical results derived.
