Abstract

A mathematical model for leakage of TNT charges is built based on Fick's law and the two-film theory in accordance with the basic process of dissolution-diffusion-desorption. This model is used to simulate numerically the leakage processes of TNT through rubber material both under water and in the air in the case of one-dimension, and the concentration distributions of explosive charges in the material at different times and the stable diffusion flux are obtained. The simulation results are consistent with the experimental data in the literature. The rationality of the model is verified. The main factors affecting the leakage process, such as coating material thickness and external medium, are analyzed. The results show that the leakage of TNT under water is easier than in the air.
