Thermal conductivity typically:
Thermal conductivity (k) measures a material's ability to conduct heat, defined by Fourier's Law: q = -k∇T where q is heat flux and ∇T is temperature gradient. Units are W/m·K.
q = -k∇T
Metals typically have k = 10-400 W/m·K, while insulators have k = 0.01-1 W/m·K.
Composite thermal conductivity depends on:
Common models include parallel (upper bound), series (lower bound), and Maxwell-Eucken.
Thermal conductivity varies with temperature due to:
