3d numerical simulation of laminar flow and conjugate heat transfer through fabric

Popis výsledku v původním jazyce

The air flow and conjugate heat transfer through fabric was investigated numerically by FLUENT package in ANSYS in this paper. The objective of this paper is to study the thermal insulation of fabrics under heat convection or the heat loss of human bodyunder different conditions (fabric structure and contact conditions between human skin and fabric). The numerical simulations were performed in laminar flow regime at constant skin temperature (310K) and constant air flow temperature (273K) at 5m/s. Someimportant parameters such as heat flux through fabrics, heat transfer coefficient, and Nusselt number were evaluated. The results showed that the average heat fluxes through fabrics were 1346.9 W m-2, 342.3 W m-2, and 2520.4 W m-2 for simulation 1, simulation 2, and simulation 3, respectively. Correspondingly, the average heat transfer coefficients were 36.4 W m 2 K 1, 9.25 W m 2 K-1, and 68.12 W m-2 K-1, respectively.
