Boiling Investigation in the Microchannel with Nano-Particles Coating

Development of Methods for Heat Transfer Enhancement During Nitrogen Boiling to Ensure Stabilization of HTS Devices

“…Interesting results are presented in [173], showing that the use of a nano-relief surface results in up to a fivefold increase in the rate of fluid circulation in a vertical channel and up to a threefold intensification of heat transfer in natural circulation at low temperature pressures of up to 5 K and pressures of up to 0.2 atm. It is also useful to present here the results obtained in [174] on liquid boiling in a single microchannel with a height of 0.2 mm, a width of 3 mm, and a length of 13.7 mm with a smooth heating surface or with a coating of aluminum oxide nanoparticles.…”

“…The regularities presented in [13][14][15][166][167][168][169][170][171][172][173][174] are important for simulation of the hydrodynamics and heat transfer processes in cryogenic thermostabilization systems using channel and minimicrochannel assemblies for coolant pumping in HTS equipment.…”
