Topics - Thermal Conductivity

Thermal Conductivity Heat can be transferred by conduction, convection or radiation. The process of transferring heat through a body is call thermal conduction. The physical property ‘thermal conductivity’ is a measure of how efficient the material will conduct heat through it. The thermal conductivity of a substance is defined as the amount of heat transferred per unit area per unit time per unit temperature gradient through a body. Mathematically, thermal conductivity can be treated in a very similar way to diffusion leading to very similar types of mathematical functions. Thermal conductivity is very important when designing for thermal insulation, thermal isolation, efficient heat transfer and cooling systems
