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.

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy ...
The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's systems in balance. A new ...
