A clear boiling delay was observed during imbibition of room temperature liquids into capillary channels, in which nucleate boiling is postponed to a temperature above the saturation temperature of the liquid. This boiling delay is also expected to influence the wicking behavior because similar effect are involved, for example the effect of surface tension, viscosity and evaporation. Wicking...
Spray cooling is the primary method for conducting chilldown and fill of cryogenic propellant tanks. In a typical spray injection process, a liquid sheet/jet that exits the spray nozzle undergoes primary breakup by the development of surface instabilities. Droplets and ligaments generated after the primary breakup undergo secondary breakup to create a dispersion of droplets, which extract heat...
To study the quenching characteristics of different materials in cryogenic liquid baths, transient temperature measurements of high accuracy are necessary. Thermocouple is an ideal tool for these applications because of their low self-heat capacity. However, they require calibration before usage. Typically multiple fixed point temperatures are used. The common fixed point temperatures are...
