Quantitative investigation of moisture migration during microwave drying of coal slime dough through simulation and tracer analysis.

ABSTRACT: Moisture migration during the microwave drying process of coal slime is critical for improving drying efficiency and reducing energy consumption. Nevertheless, current methods for quantifying these migration behaviors remain insufficient. In this research, we employed a comprehensive approach that combines experimental investigations with multi-physical field simulations to quantitatively characterize the distribution and state of moisture within coal slime dough at different locations during microwave drying. The entire drying process was divided into three distinct stages based on temperature distribution: preheating, constant temperature, and reheating. During the preheating stage, as temperature rose, more than 74.1% of the initial water content within the central region of the slime d
