CHEE2695 – Lecture 3
Fourier’s Law:
- Heat transfer rate is directly related to the temperature gradient
- The temperature and special coordinate are both independent.
General conductive energy equation:
- Consider a control volume contained within a larger volume of dimensions x,
y, and z.
- First, the energy flows in and out must be balanced.
- P represents the difference of the rate of energy generation and energy
stored, P=E G−E S.
- Combining these gives the above equation.
