Study Notes
Heat Transfer Basics
- The driving force for heat energy in transit is a temperature difference.
- According to the Law of Thermodynamics, heat flows from a body at higher temperature to a body at lower temperature.
- When two bodies attain equilibrium of temperature, the flow of heat energy stops.
Engineering Considerations
- Engineers are concerned with quantifying and controlling heat transfer in various applications.
- Knowledge of heat transfer is applied across numerous fields, including mechanical engineering, chemical engineering, aerospace engineering, and civil engineering.
Modes of Heat Transfer
- Conduction, convection, and radiation are the three primary modes of heat transfer.
- Conduction involves heat transfer through direct contact between substances.
- Convection involves heat transfer through the movement of fluids (liquids and gases).
- Radiation involves heat transfer via electromagnetic waves.
Additional Considerations
- Heat energy will flow when there is a temperature difference between two bodies.
- Heat transfer is fundamentally based on the Law of Thermodynamics.
- The capacity to do work is called energy.
