Significance of thermal diffusivity
WebThermal diffusivity: It is defined as the ratio of thermal conductivity and thermal capacity of the material. T h e r m a l d i f f u s i v i t y ( α) = T h e r m a l C o n d u c t v i t y ( K) T h e r m a l C a p a c i t y ( ρ C) It signifies the ability of a substance to conduct heat relative to its ability to store thermal energy. WebThermal diffusion definition, the separation of constituents, often isotopes, of a fluid under the influence of a temperature gradient. See more.
