Analysis of the heat transfer property with the sandwich fabrics based on ANSYS workbench and Alambeta

Abstract

As more and more attention is paid to the thermal comfort of clothing, academic research on the heat transfer properties of textile materials is becoming more and more important. In recent years, the application of simulation software to analyze the heat transfer properties of fabrics has become a research hotspot. In this paper, the ANSYS workbench simulation software is used to simulate the heat transfer property of a kind of sandwich fabric. The results obtained by establishing different models show that the application of single-layer fabric with different thermal resistances in the sandwich fabric will lead to greatly different thermal resistances of sandwich fabric; the same material has different thicknesses, and its thermal resistance will increase with the thickness; the same single-layer fabric with different combination positions will cause the thermal resistance of the sandwich fabric to change. At the same time, the software simulation values are compared with the actual measured values. It can be found that the two sets of data have the same trend, but the data of the former is significantly higher than the latter. The reason is that the model's porosity is much smaller than the actual sample.
