The heat flux from the internal bag gas to the air bag fabric due to internal surface convection is addressed. How this heat flux may be differentiated from the other modes of internal bag gas heat loss, such as the mass flux through the permeable fabric and vents is also discussed. To this end, an experimental apparatus is designed to approximate the dominant gas flow characteristics near the fabric during deployment. A one-dimensional numerical model utilizing conservation principles is developed and used to predict the experimental results. Fair agreement is found between the predictions and experimental results.
