Abstract: The operation of a LN2 cryogenic heat pipe has been demonstrated experimentally in the range 78 K to 90 K. This heat pipe involves a totally new wick concept, viz., the “parallel capillary ...

Abstract: A thermal conductivity measurement technique has been developed based on a novel design employing an ultrafine (0.02 cm dia) “traversing” thermocouple. This technique features the rapid determination ...
