ARTICLE J. Cent. South Univ. (2019) 26: 2129-2135 DOI: https://doi.org/10.1007/s11771-019-4160-1 Effects of TiO2 nanoparticles on thermal conductivity of heat transfer oil YIN Xiang(尹湘), KOU Guang..., part of Springer Nature 2019 Abstract: There is a lack of thermophysical data of heat transfer oil and nano-oil in the high temperature range of 50-300 °C for designing and developing heat transfer......
powder reaction bed depends strongly on the effect of heat transfer, mass transfer and intrinsic reaction together. The reaction bed with the porosity of 0.53 exhibits the largest hydrogenation rate... high even for a long time, which promotes fast heat transfer. The further analysis indicates that more emphases should be put on heat transfer rate rather than the only improvement of the effective......
used to meet the great challenge of heat transfer inside sophisticated electronics. Oscillating and pulsating phenomena play a great role in the field of heat transfer to control heat transfer... fluctuation occurs because of nucleate boiling by evaporative section and condensation of the working fluid. Oscillating heat pipe can transfer heat in quick response in any orientation. This work shows all......
