The Brinkman number (Br) is a dimensionless quantity in fluid mechanics and heat transfer that characterizes the relative importance of viscous dissipation to thermal conduction in a fluid flow. It is commonly used in the study of flow in porous media or in situations where the flow is significantly affected by both viscous forces and thermal effects.
