摘要: The paper outlines a formulation of the cylindrical transport equations which describe simultaneous heat and mass transfer in unsaturated porous materials when line resource is embedded medium. A macroscopic continuum mechanics approach adopted to derive coupled continuity, momentum energy equations. Hydrodynamic law such as Darcy's Darcy-Buckingham theorem are utilized simplify continuity fluid flow. Migration liquid due surface tension effects modeled analysis. phase change on also included equation. constituent expanded co-ordinate system. resulting reported this found agree with obtained by other researchers who used volume-averaging techniques study similar phenomena materials.
