Importance of thermal diffusivity
WitrynaThermal diffusivity is one of the important concepts in the heat transfer process. Thermal diffusivity is defined as the rate of temperature spread through a material. It … WitrynaThe advantages of having low thermal diffusivity can be quite obvious in some use cases. In the aerospace industry, synthetic foams and epoxies have been developed with very low thermal diffusivities for use in rocket ships. These foams have low densities and help to prevent structural damage to the rockets upon atmospheric reentry.
