Understanding Heat and Mass Transfer
What is Heat Transfer?
Heat transfer refers to the movement of thermal energy from one physical system to another. It occurs in three primary modes:
1. Conduction - The transfer of heat through a material without any motion of the material itself. It typically occurs in solids.
2. Convection - The transfer of heat through a fluid (liquid or gas) caused by the fluid's motion. This can be natural (due to buoyancy) or forced (using pumps or fans).
3. Radiation - The transfer of heat in the form of electromagnetic waves. This can occur in a vacuum and does not require a medium.
What is Mass Transfer?
Mass transfer involves the movement of mass from one location to another, which is essential in various processes such as chemical reactions, evaporation, and absorption. It can occur in multiple ways:
1. Diffusion - The process by which molecules spread from areas of high concentration to areas of low concentration.
2. Convection - Similar to heat transfer, mass transfer can also occur through fluid motion.
3. Advection - The transport of substances by the bulk motion of a fluid.
