“…While the analysis correlated well for subcooled liquid methane, Jurns and McQuillen (2008) found that this correction term did not hold when applied to results for subcooled liquid oxygen over the same small deviation from a saturated state. While there are reported values for LH at saturation pressures near standard conditions using gaseous helium (GHe) as the pressurant gas, as well as storable fluids such as IPA and Freon-112 as reported by Paynter (1973), Burge and Blackmon (1973), Cady (1973), Cady (1975), Cady (1977), Chato and Kudlac (2002), Kudlac and Jurns (2005), and Jurns et. al (2007).…”

“…Wicking as the imbibition of a wetting fluid into porous wicks under capillary suction pressure has been investigated widely as it appears in a wide range of applications such as in propellant management devices and in liquid acquisition devices of space crafts, in the commercial plug‐in devices for fragrance dispersion in rooms, in the TIKI torches used during camping, and in many other applications. In such applications, it often becomes necessary to optimize the performance of wicks, and one may use analytical models for this purpose …”

Flow along and across glass‐fiber wicks: Testing of permeability models through experiments and simulations

2018

A rigorous test of important theoretical models for permeability of glass‐fiber wicks, backed by numerical simulations, is conducted using a novel small‐scale experiment. The models include those for flow along and across aligned fibers and for flow through random fibers. The domains for numerical simulations were created by randomly distributed parallel fibers in a cube‐like unit‐cell using Geodict. Two separate simulations were considered: (1) Stokes‐flow solution using GeoDict, (2) Whitaker's closure‐formulation solution using COMSOL. The falling‐head parameter was adapted to measure the permeability along and across the fibers. Multiple measurements were conducted for each of the wicks to establish repeatability and estimate scatter. The permeabilities obtained through experiments matched with those from the theoretical and numerical methods. But numerical permeabilities for the longitudinal flow were exceptionally accurate. Also, the specialized models for longitudinal and transverse flows were more accurate than the random‐fiber models. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3491–3501, 2018

“…[1][2]13 One promising concept for propellants that can be pressurized with their own vapor (such as oxygen and hydrogen) is a procedure known as no-vent fill. 12,13 This procedure uses liquid subcooling to re-condense vapor back into the incoming liquid. For tanks, which are warm and dry, a chilldown procedure is used to remove wall energy and a sacrificial quantity of cryogen is vented overboard as vapor prior to the start of the transfer.…”
