A NUMERICAL STUDY OF NONISOTHERMAL REACTIVE FLOW IN A DUAL-SCALE POROUS MEDIUM UNDER PARTIAL SATURATION

ABSTRACT This numerical study investigates the temperature and cure distribution during the flow of a reactive liquid in dual-scale fibrous porous media under partial saturation. An iterative, control-volume approach, based on energy and cure balances, is used for developing discretized equations in the channels and fiber tows of the two-layer model of a dual-scale porous medium. Significant differences in the average temperatures and cures within the channels and fiber tows are observed. The ratio of the channel and fiber-tow pore volumes, the ratio of liquid and fiber heat capacities, the fiber-bundle thermal conductivity, along with the reaction rate are identified as the important parameters for temperature and cure distributions.
