Résumé

The thermal conductivity of polyurethane foam in the temperature range between 300 and 20 K is investigated theoretically and experimentally for the development of liquid hydrogen storage tanks. An experimental set-up based on the JIS standard A1412 is built to measure the thermal conductivity of the foams under various temperature and pressure conditions. An analytical model, including the contributions from radiative heat transfer, is used to predict the thermal conductivity of the polyurethane foams.
