Detailed Description

Solve energy conservation equation.

• Energy conservation equation in terms of temperature

  \[ \left( {\phi {\rho _f}{c_{pf}} + \left( {1 - \phi } \right){\rho _r}{c_{pr}}} \right)\frac{{\partial T}}{{\partial t}} = \nabla \cdot \left( {{\lambda _r}\nabla T} \right) - {\rho _f}{c_{pf}} \vec{v} \cdot \nabla T + \frac{{{\mu _f}}}{k}{\vec{v}^2} - {\left( {\frac{{\partial \;ln\rho }}{{\partial \;lnT}}} \right)_p}\frac{{Dp}}{{Dt}} \]

  where \( \left( {\frac{{\partial \;ln\rho }}{{\partial \;lnT}}} \right)_p = -T\alpha_p \), \( \alpha_p \) is the fluid thermal expansivity.
• Energy conservation equation in terms of enthalpy
