Heat Transfer Mechanisms

Thermal analysis involves three primary heat transfer mechanisms:

  • Conduction: Heat transfer through solid materials
  • Convection: Heat transfer through fluids (liquids and gases)
  • Radiation: Heat transfer through electromagnetic waves

Each mechanism follows different physical laws and requires specific calculation approaches.

Key Thermal Parameters

Important parameters in thermal analysis include:

  • Thermal Conductivity (k): Material's ability to conduct heat
  • Heat Transfer Coefficient (h): Convective heat transfer rate
  • Overall U-value: Combined heat transfer coefficient
  • Log Mean Temperature Difference (LMTD): Driving force in heat exchangers
