“…If a permanent gas is bubbled into a liquid, the liquid will vaporize into the gas bubbles, and the latent heat requirement can be sufficient to appreciably lower the liquid temperature. This effect is used, for example, to maintain liquid oxygen in a subcooled state before rocket launch by bubbling helium gas into the oxygen container (see, e.g., Cho et al 2006, Jung et al 2014.…”

This article reviews the fundamental physics of vapor bubbles in liquids. Work on bubble growth and condensation for stationary and translating bubbles is summarized and the differences with bubbles containing a permanent gas stressed. In particular, it is shown that the natural frequency of a vapor bubble is proportional not to the inverse radius, as for a gas bubble, but to the inverse radius raised to the power 2/3. Permanent gas dissolved in the liquid diffuses into the bubble with strong effects on its dynamics. The effects of the diffusion of heat and mass on the propagation of pressure waves in a vaporous bubbly liquid are discussed. Other topics briefly touched on include thermocapillary flow, plasmonic nanobubbles, and vapor bubbles in an immiscible liquid.

“…Liquid oxygen is more widely used than all the other atmospheric gases combined in civilian and military fields. 1 In the civilian field, liquid oxygen has attracted much attention for industrial and medical purposes, while in the military field, due to high-specific impulse, liquid oxygen is a common liquid oxidizer propellant for spacecraft and is usually used in combination with liquid hydrogen or kerosene. 2,3 However, during its production, transport, and use, oxygen is in contact with many different materials, virtually all of which will burn.…”

The bromine element was introduced into an epoxy resin to improve the liquid oxygen compatibility of the epoxy resin. After curing using 4,4′-diamino diphenylmethane, the liquid oxygen compatibility of all specimens was measured by the liquid oxygen mechanical impact test (ASTM D2512-95). The results suggested that the bromine-modified epoxy resin (BEP) was compatible with liquid oxygen, whereas the bisphenol F epoxy resin (EP) had poor liquid oxygen compatibility. The results of thermogravimetric analysis indicated that the incorporation of tetrabromobisphenol A into EP could accelerate the second-stage thermal degradation of BEP, leading to improvement of the liquid oxygen compatibility. X-ray photoelectron spectroscopy analysis indicated that the C–C/H groups on the surface of specimens could be oxidized to C–O–H/C and C=O groups during the impact process. The mechanism of bromine enhancement on the liquid oxygen compatibility of epoxy resin is proposed.
