Combined boundary and inertia effects for fully developed mixed convection in a vertical channel embedded in porous media
- Tatung Inst. of Tech., Taipei (Taiwan, Province of China)
The fully developed laminar mixed convection in a vertical channel embedded in porous media has been solved by using non-Darcy flow model. Through proper manipulation of nondimensional variables and parameters, the governing equations are derived and the thermal boundary conditions on the left and right walls can be prescribed as isothermal-isothermal, isothermal-isoflux, or isoflux-isothermal, respectively. Including the Darcian force, buoyancy force and boundary effect, the exact solutions for temperature and velocity profiles are obtained. Meanwhile, parametric zones for the occurrence of flow reversal based on the analytical solutions are presented. Finally, the numerical solution is also provided to investigate their further influence due to the existence of inertia effect.
