Issue Date : July 2020• In order to include the boiling effect, several different subroutines which model evaporation and condensation phenomena were attached to the solver. Heat transfer in boiling cryogenic liquids progress in cryogenic technology and increased demands on the precision in calculations of the quenching regime have revived an interest in transition boiling.
A drop-tower technique is used to achieve the reduced gravities. Received : 28 February 2020• Heat Mass Transfer 43, 114—121 2000. The problems of heat transfer enhancement in channels for film boiling are introduced. The quenching efficiency was found to increase with increasing number of coating layers, and the efficiency also increased with decreasing mass flow rates.
Nellis, Cryogenic Heat Transfer, 2nd ed. For each of aband cthe left plot is for no coating, the middle plot is for a 1L coating, and the right plot is for a 4L coating.
Advances in Cryogenic Engineering, vol 21. Publisher Name Springer, Boston, MA• Numerical Simulation of Heat Transfer During Boiling Flow of Cryogenic Fluid in Vertical Tube. Comparison with experimental data shows that the modified model is satisfactorily improved in accuracy.
Then boiling flow of liquid nitrogen in a vertical tube was numerically simulated using the modified basic model. Four coating thicknesses with various coolant mass flow rates of liquid nitrogen were investigated.
40 6745—750 2019. A study is reported of boiling heat transfer with saturated liquid nitrogen under atmospheric pressure at standard, fractional, and near-zero gravity. Published : 16 October 2020• Abstract The two-fluid model has been extensively used in modeling boiling flow of water, however, there are few equivalent studies of boiling flow of cryogenic liquids.
Boiling curves for different coatings at the T6 location bottom TC, downstream location. Comparing to the bare surface case, the percentage increase in the quenching efficiency was the minimum at 4.
The quenching efficiency was found to increase with increasing number of coating layers, and the efficiency also increased with decreasing mass flow rates.
