A multi-scale study of the performance of protective clothing has been performed by coupling various types of numerical simulation of flow, heat and mass transfer. From meso-scale Direct Numerical Simulation, it was found that the flow underneath the clothing is laminar and periodic, with a magnitude much smaller than the free stream velocity. Micro-scale Direct Numerical Simulation revealed a simple relation between textile porosity and permeability. A good agreement was found between flow and heat transfer predictions of Direct Numerical Simulation and Reynolds Averaged simulation. From the latter, an engineering correlation for heat and mass transfer was deduced.
