The effect of gravity on cryogenic transfer line chilldown performance using pulse flow and low thermally conductive coatings

•Reduced gravity cryogenic line chilldown data presented.•Investigation is carried out on effect of low thermally conductive coatings and pulse flow.•Comparisons are made between 1-g and reduced gravity for similar conditions.•No appreciable degradation in chilldown efficiency at moderate-to-high Reynolds numbers in reduced gravity relative to terrestrial gravity.
