PRINCIPLES OF EVACUATED CRYOGENIC INSULATIONS

The physical principles associated with heat and mass transfer in the various evacuated insulations employed in cryogenic systems (e.g., LNG storage vessels) are reviewed, including gaseous and solid conduction and radiation heat transfer in evacuated powders and fibrous materials, opacified powders, and multilayer insulations; the effects of powder density on the thermal conductivity of evacuated powders; the effects of lateral conduction, compressive loading, and perforations on thermal conductivity in multilayer insulations; and mass transfer in multilayer insulations during evaluation.
