Understanding Heat and Mass Transfer
Heat transfer is the process by which thermal energy moves from one body or system to another due to temperature differences. Mass transfer, on the other hand, involves the movement of mass from one location to another, often driven by concentration gradients. The two processes are interconnected, especially in systems where thermal energy influences mass movement and vice versa.
Key Concepts in Heat Transfer
1. Conduction: The transfer of heat through a solid material without any motion of the material itself. Fourier's law describes this process.
2. Convection: The transfer of heat through fluids (liquids or gases) due to the motion of the fluid itself. This can be classified as natural convection and forced convection.
3. Radiation: The transfer of energy through electromagnetic waves. All objects emit radiation depending on their temperature.
Key Concepts in Mass Transfer
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 via convection in fluids.
3. Absorption and Adsorption: Processes where one substance becomes incorporated into another.
