On the Darcy-Brinkman-Boussinesq flow through a thin channel with slightly perturbed boundary

This is a joint work with Prof. Eduard Marušić- Paloka and Prof. Igor Pažanin. In this talk, we will investigate the effects of a small boundary perturbation on the non- isothermal fluid flow through a thin channel filled with porous medium. Starting from the Darcy-Brinkman-Boussinesq system of equations and employing methods of asymptotic analysis, we derive a higher-order effective model given by the explicit formulae. To observe the effects of the boundary irregularities, we numerically visualize the asymptotic approximation for the temperature, whereas the justification and the order of accuracy of the model is provided by the theoretical error analysis.
