Thermal effusivity

In Thermodynamics, the thermal effusivity of a material is defined as the square root of the product of the material's thermal conductivity and its volumetric heat capacity.[1]

e = {(k\rho c_p)}^{1/2}

Here, k is the thermal conductivity, ρ is the density and cp is the specific heat capacity. The product of ρ and cp is known as the volumetric heat capacity.

A material's thermal effusivity is a measure of its ability to exchange thermal energy with its surroundings.
