Abstract: In this paper, we report on experimental results to measure the total temperature of nitrogen gas at the inlet and outlet of microtubes with constant wall temperature and to quantitatively determine the heat transfer rates. ...

Abstract: Abstract. This study investigates the effect of compressibility on the kinetic energy correction factor, α, in both laminar and turbulent gaseous flows. In Bernoulli's equation, α is defined as the ratio of kinetic energy ...

Abstract: Many previous studies used the performance factors for the evaluation of heat transfer enhancement of nanofluids under the identical pumping power. The validity of the performance factors was not examined yet. The validity ...
