Thermal conductivity (k) measures a material's ability to conduct heat, defined by Fourier's Law:
Where:
q = heat flux (W/m²)
k = thermal conductivity (W/m·K)
∇T = temperature gradient (K/m)
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:
Shell and tube exchanger calculations
Analyze heat transfer in reactors
Material expansion calculations
