Heat transfer is the transmission of thermal energy from one region to another as a result of a temperature difference.
Types of Heat Transfer
Two types of heat transfer analysis:
- Steady state thermal analysis
- Focuses on the thermal conditions of the body when it reaches thermal equilibrium. The time it takes to reach thermal equilibrium is not of interest.
- Transient thermal analysis
- Focuses on the thermal status of the body at different instances of time.
Thermal stress analysis
Temperature changes can induce significant stresses in the body. Thermal stress analysis calculates stresses, strains, and displacements due to thermal effects.
