A source of thermal energy (heat) E_H with a reference to location in 3D space.
The quantitative value is given by the pace of thermal energy variation (production or consumption) per unit time:
| (1) | W_H({\bf r}) = \frac{\delta E_H}{\delta t} |
where
{\bf r} | position vector in 3D space |
The total volume of Heat Source contained in a given volume \Omega can be calculated as:
| (2) | W_H({\bf r}) = \int_{\Omega} q_H({\bf r}) d V |
where
q_H({\bf r}) | Heat Source Density at point
{\bf r} |
