Determination of Radiative Thermal Conductivity in Needlepunched Nonwovens
Radiative Thermal Conductivity Needlepunched Nonwovens
2009/7/21
Radiation heat transfer is found to be the dominant mode of heat transfer at temperatures higher than 400-500K [11]. Convection heat transfer being negligible in nonwovens, effective thermal conductiv...
