Thermal Conductivity and Contact Conductance of Explosafe
The thermal conductivity of EXPLOSAFE*, an expanded aluminum foil used to augment the heat transfer in a pressure vessel, was measured over a temperature range of 5°–70° C. Measurements were obtained with different styles, orientations and thicknesses of EXPLOSAFE. In addition, the thermal contact conductance for an EXPLOSAFE matrix and wall interface was determined for one particular style as a function of pressure and a simple correlation developed.
A guarded hot-plate apparatus with an on-line Microcomputer (Hewlett Packard-85) and the Hewlett Packard-3497 Data Acquisition System was used.
