This text investigates the fundamental mathematical and physical principles governing the transport of mass, momentum, and energy through porous structures. Howard Brenner, a recognized authority in chemical engineering and fluid mechanics, utilizes a rigorous analytical framework to derive macroscopic transport equations from microscopic physical laws. The book focuses on the transition from local pore-level phenomena to global behavior in complex, heterogeneous media.

Experts identify this work as a foundational text for graduate-level chemical and mechanical engineering students. Readers frequently note the high level of mathematical density and the rigorous theoretical approach required to fully grasp the presented derivations.
