The Study of Footwear Thermal Insulation Using Thermography and the Finite Volume Method

Abstract

The paper concerned the issue of ergonomics and thermal comfort of footwear. The presented work was an attempt to apply selected modeling CAD software and the finite volume method for analysis of heat transfer through footwear between the shoes' user and his surroundings. Based on the actual two selected sport shoes, three-dimensional models have been designed, taking into account their different geometry and raw material composition. The models used simplifications related to the internal construction (in microscale) of the specific parts of the footwear (sole, insole, shank, lining and tongue). The main purpose of the work was to determine the influence of the simplifications used on the accuracy of simulation as a tool to predict thermal insulation of real shoes determined by means of thermal imaging camera. The simulations results were in correlation with the experiment and showed that applied software can be an effective tool in studying the thermophysiological properties of footwear.

Analysis of the Thermal Insulation of Textiles Using Thermography and CFD Simulation Based on Micro-CT Models

“…In research described in earlier articles [14][15][16][17][18][19][20], the physical properties of clothing textiles were modeled using simulations of physical phenomena in 3D models of real textiles. These models were designed in the Solidworks CAD software based on the geometric parameters of actual textiles, determined using SEM images, which were analyzed with the ImageJ software (see "First approach of modeling" in Figure 2).…”

“…The work reported in the current article is related to the important problem of thermal comfort and is a continuation of the work on modeling physical phenomena related to the ergonomics of clothing [14][15][16][17][18][19][20]. In these related six articles, the physical properties of clothing textiles have been studied based on simulations of physical phenomena using 3D models of real textiles.…”

Assessment of the Impact of Clothing Structures for Premature Babies on Biophysical Properties

“…Currently, numerical modeling is an effective and widely used tool to investigate thermal and mechanical processes occurring in textiles, among other things [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. In the current work, the experimental research was supplemented by the simulation of the thermal insulation of the assemblies by designing their 3D models using selected CAD software and applying the finite volume method.…”

Modeling of thermal performance of multilayer protective clothing exposed to radiant heat

“…In the current work selected CAD software and finite volume methods to analyze heat transfer in protective clothing in order to predict its protection performance was applied. The work is continuation of research using the software to model physical phenomena occurred in functional clothing [2,36,37]. However, the mentioned articles concerned simulations of heat transfer performed under steady state conditions.…”
