Dynamics simulation analysis of the melting process of ice on the surface of aramid IIIA fabrics

In many industries, workers are facing the inconvenience caused by icing on fabrics. Fabric is a porous material, and researchers generally hold that porous material is not suitable for being used as an anti-icing material. Therefore, research on the anti-icing properties of fabrics have not attracted researchers' attention, thus relevant research results are few. The influence of sample surface wettability on snow melting has been rarely studied in depth. In this paper, a test device for testing the melting rate of ice on the surface of a sample was developed. Based on this experiment, a simulation model for simulating the melting process of the ice on the aramid IIIA fabric samples was established based on the melting promoting anti-icing theory. This work also indicates that the use of computational models in the study of ice melting processes is successful. Results show that the relative error between the simulated value and the experimental value was 1.63%. These computational models provide details on the phase transition and temperature changes of ice during the melting process, which are difficult to observe in experiments. Meanwhile, the simulated phase transition of ice is consistent with actual observations. The results indicate that the simulation model established in this article can be extended to study the melting process of ice on aramid IIIA fabric samples, and can be used to guide the study of the anti-icing performance of aramid IIIA fabrics.
