“…Advances over Aydelott included actual heat transfer data by using a condensing fluid (refrigerant 113) and longer duration. Bentz [1][2][3] was able to confirm the geysering and circulating regimes of Aydelott, but encountered an asymmetric regime between the two that was even lower heat transfer than aft collection, the lowest mixing regime of Aydelott. The second flight of TPCE focused mostly on rapid boiling phenomena, but contains some further tests on mixing.…”

“…In normal gravity the gravitational force controls and restricts the liquid jet flow, but in microgravity jets must be contained by surface tension forces. Recent NASA experiments in microgravity [1][2][3][4][5][6] have brought a wealth of data of jet behavior in microgravity. The Vented Tank Resupply Experiment [6] was surprising in that although it contained a complex geometry of baffles and vanes the limit on liquid inflow was the emergence of a liquid jet from the top of the vane structure.…”

“…Notable experiments include: Storable Fluid Management Device (SFMD)/Fluid Acquisition and Resupply Experiment (FARE), which used a common set of hardware to explore several different transfer schemes; [14][15][16][17] Tank Pressure Control Experiment (TPCE), [18][19][20][21][22] which examined pressure control and tank mixing; and Vented Tank Resupply Experiment (VTRE), 23 which looked at a vane device to separate gas and liquid during transfer. The super fluid on-orbit transfer (SHOOT) flight demonstration, 24 was very successful in moving superfluid helium from tank to tank on-orbit.…”

“…All of these studies provide strong indications that enhanced heat and mass transfer between ullage gas and cryogenic liquid propellant does cause significant collapsing (with associated pressure reduction) of the ullage gas. A number of studies [68][69][70][71][72][73][74][75][76][77][78] provides empirical data showing ullage gas collapse through this enhanced heat and mass transfer.…”

One of the major technical problems associated with cryogenic liquid propellant systems used to supply rocket engines and their subassemblies and components is the phenomenon of propellant tank pressurant and ullage gas collapse. This collapse is mainly caused by heat transfer from ullage gas to tank walls and interfacing propellant, which are both at temperatures well below those of this gas. Mass transfer between ullage gas and cryogenic propellant can also occur and have minor to significant secondary effects that can increase or decrease ullage gas collapse. Pressurant gas is supplied into cryogenic propellant tanks in order to initially pressurize these tanks and then maintain required pressures as propellant is expelled from these tanks. The net effect of pressurant and ullage gas collapse is increased total mass and mass flow rate requirements of pressurant gases. For flight vehicles this leads to significant and undesirable weight penalties. For rocket engine component and subassembly ground test facilities this results in significantly increased facility hardware, construction, and operational costs. "Collapse Factor" is a parameter used to quantify the pressurant and ullage gas collapse. Accurate prediction of collapse factors, through analytical methods and modeling tools, and collection and evaluation of collapse factor data has evolved over the years since the start of space exploration programs in the 1950's. Through the years, numerous documents have been published to preserve results of studies associated with the collapse factor phenomenon. This paper presents a summary and selected details of prior literature that document the aforementioned studies. Additionally other literature that present studies and results of heat and mass transfer processes, related to or providing important insights or analytical methods for the studies of collapse factor, are presented.
