Abstract

In recent years, an integrated analysis of computational fluid dynamics (CFD) and computer simulation person (CSP), especially to reproduce the shape of the human body, has been conducted to estimate the interaction between the human body and its surrounding indoor environment. Meanwhile, clothing is often treated in a simplified manner, as a means of resistance to heat and pollutant transfer, and there is sufficient room for improvement in the hygrothermal and scalar transfer phenomena in and around clothing with a complex geometry. In this study, some garment models with complex geometry and others with simplified geometry were created with a CSP, and airflow, temperature, and humidity were investigated along with the CSP. It was assumed that only heat and water vapor were transported in the garment. As a result, the naked model was found to be over-or underestimated with respect to all airflow, temperature, and water vapor. It was also found that models with a simple garment shape produced the same results as models with a complex geometry on a macroscopic scale. Models with different regions and smaller air gaps between the clothes and the human body should be confirmed.
