✦ Synopsis

The effective thermal conductivities of silica aerogel foam [0.1 (10)-3 kg m -3 nominal density] filled with liquid n-H 2, liquid n-D 2 and an equimolar mixture of liquid H2-D 2 were measured near 19.6 K. Our measured value of 97 mW m -1 K -~ for hydrogen filled foam is essentially the same as for the liquid alone. This result agrees with predictions for the thermal conductivity of porous systems which give a 2% enhancement in the effective thermal conductivity for this system relative to the liquid alone.
