Introduction to Transport Phenomena

Transport phenomenaA field of engineering that studies mass, energy, and momentum within and between systems are the fundamental processes that govern the movement of heat, mass, and momentum within and between systems. These processes play a crucial role in determining the behavior of systems and predicting their performance. Transport phenomena are studied in a wide range of fields, including chemical engineering, materials science, and biology.

Heat transport refers to the movement of thermal energy from one location to another. This can be achieved through three main mechanisms: conduction, convection, and radiation. Conduction refers to the transfer of heat through a material by the collision of atoms or molecules. Convection refers to the transfer of heat by the movement of a fluid or gas. Radiation refers to the transfer of heat through electromagnetic waves.

Mass transport refers to the movement of matter from one location to another. This can be achieved through three main mechanisms: diffusion, convection, and mass transfer. Diffusion refers to the movement of molecules from an area of higher concentration to an area of lower concentration. Convection refers to the movement of a fluid or gas that carries molecules along with it. Mass transfer refers to the transfer of molecules from one phase to another, such as from a liquid to a gas.

Momentum transport refers to the movement of momentum from one location to another. This can be achieved through two main mechanisms: fluid flow and the transfer of momentum between particles. Fluid flow refers to the movement of a fluid or gas, which carries momentum along with it. The transfer of momentum between particles refers to the transfer of momentum between atoms or molecules in a system.
