Transport phenomena is a research area concerned with the fundamental mechanisms and coupled behavior of momentum, heat, and mass transfer in physical, chemical, and biological systems. It formulates and analyzes balance equations derived from conservation laws, typically expressed as partial differential equations such as the Navier–Stokes, energy, and species transport equations. The field emphasizes constitutive relations (e.g., Newton’s law of viscosity, Fourier’s law of heat conduction, Fick’s law of diffusion) and dimensionless analysis to characterize regimes and scaling. Transport phenomena underpins modeling, simulation, and optimization across chemical engineering, materials processing, microfluidics, energy systems, and physiological flows.
Control of heat transport in nanostructures is of central importance for numerous modern technologies—from high-performance computer chips that need to be cooled to energy converters—and is a highly active area of research. ...
