Heat Transfer
Heat transfer is the movement of thermal energy from higher to lower temperature regions through three mechanisms:
- Conduction: Direct molecular transfer
- Convection: Fluid motion transfer
- Radiation: Electromagnetic waves
Conduction Formulas
Fourier's law
Thermal resistance
Design Tips
• Choose appropriate material properties
• Consider heat transfer enhancement
• Account for temperature variations
• Validate with experimental data
• Consider economic optimization
