... to suggest a gas-independent correlation function between the response time and flow rate. In particular, the numerical data augmented by the theoretical analysis to account for the wire response time is validated against experimental data and used to further enhance the experimental data set. Nitrogen...

... effect on synchronous rotating cavitation, we conducted experiments in which liquid nitrogen was set at different temperatures ( 74 K , 78 K , and 83 K ). We clarified the thermodynamic effect on synchronous rotating cavitation in terms of cavity length, fluid force, and liquid temperature. Synchronous...

.... For this reason, we estimated the cavity region in liquid nitrogen based on measurements of the pressure fluctuation near the blade tip. In the present study, we focused on the length of the tip cavitation as a cavitation indicator. Comparison of the tip cavity length in liquid nitrogen ( 80 K ) with that in cold...

...Antonio Campo; Salah Chikh; Shyam S. Sablani With the goal of intensifying turbulent free convection from heated vertical plates to cold gases, five binary gas mixtures are examined in this technical note. Helium (He) is chosen as the principal gas while xenon (Xe), nitrogen ( N 2 ) , oxygen ( O 2...

...Ashvin Hosangadi, Principal Scientist; Vineet Ahuja, Research Scientist Numerical simulations of cavitation in liquid nitrogen and liquid hydrogen are presented; they represent a broader class of problems where the fluid is operating close to its critical temperature and thermal effects...

...Peter M.-Y. Chung; Masahiro Kawaji; Akimaro Kawahara; Yuichi Shibata An adiabatic experiment was conducted to investigate the effect of channel geometry on gas-liquid two-phase flow characteristics in horizontal microchannels. A water-nitrogen gas mixture was pumped through a 96 μm square...
