Abstract
We consider the differential equations that describe the Darcy–Brinkman flow. We provide the Lie symmetry classification of this system, construct conservation laws and study the system that describes the traveling wave solutions. We show that the integration of the last system is reducible to the Abel ordinary differential equation and indicate a case when this ordinary differential equation (ODE) is integrable in quadratures.
