Arsenic (As), chromium (Cr), and vanadium (V) are naturally occurring, redox-active
elements that can become human health hazards when they are released from aquifer …

A closed expression for the average pressure difference (often called the macroscopic
dynamic capillary pressure in the literature) is proposed for two-phase, Newtonian …

Carreau fluids occur routinely in porous medium systems for a range of applications, and the
dependence of the viscosity for such fluids on the rate of strain tensor poses challenges to …

Pressure is important in virtually all problems in fluid dynamics from macro-scale to
micro/nano-scale flows. Although technologies are well developed for its measurement at …

The growth and treatment of tumors is an important problem to society that involves the
manifestation of cellular phenomena at length scales on the order of centimeters. Continuum …

Resolving pore-scale transient flow dynamics is crucial to understanding the physics
underlying multiphase flow in porous media and informing large-scale predictive models …

Salt in groundwater is brought up by capillary action, and can penetrate into the
infrastructure of any building or structure within its reach. This leads to the destruction of …

Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes
containing speculation, on a civil engineering topic of general interest and relevance to the …

Traditional models of two-fluid flow through porous media at the macroscale have existed for
nearly a century. These phenomenological models are not firmly connected to the …

Abstract Generalized Newtonian fluids (GNFs), for which the viscosity of the fluid is shear-
rate dependent, appear regularly in polymeric, geological, and biological flows, making …
