Heat Transfer
Conduction, convection, radiation; thermal resistance
About this tool
Steady heat transfer for the three classical modes.
Modes
- Conduction:
Q = k · A · ΔT / L; reports U-value. - Convection:
Q = h · A · ΔT. - Radiation:
Q = ε · σ · A · (T₁⁴ − T₂⁴)with σ = 5.670374×10⁻⁸ W/m²K⁴.
Material and flow presets are provided. Thermal resistance R = ΔT/Q is reported in all modes.
