In this article, the flow distribution of the Chinese No. 3 jet fuel in parallel minichannels heat exchanger under high temperature condition was investigated. The models of PFR and choked flow were established based on the real fluid model. The formation mechanism of flow maldistribution of the fuel in the freely distributed channels was studied. It was found that: under low heat flux, the slight flow rate deviation will be spontaneously eliminated; under high heat flux, the slight deviation of flow rate and heat flux will be enlarged and result in the channel with smaller flow rate entering the coking region. The feasibility and influence factors of the control method of flow distribution based on choked flow were discussed. The experimental results indicated that the minichannels fuel‐cooled plate with choked flow could maintain uniform flow distribution when the total fuel outlet temperature reached 1035 K. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2781–2791, 2018

“…At supercritical pressures, either heat transfer enhancement (HTE) or heat transfer deterioration (HTD) may occur. Some of the experiments observed no heat transfer deterioration, but Zhu et al [13] , Dang et al [14] , Zhao et al [15] and Li et al [16] did. They found the deterioration of the heat transfer occurred when the inner wall temperature or the fluid temperature was close to the pseudo-critical point.…”

Heat transfer performances of aviation kerosene flowing in mini tubes at supercritical pressures were investigated experimentally and numerically. A ten-species surrogate model with the extended correponding state was used to calculate the thermophysical and transport properties of kerosene and the Re-Normalization Group (RNG) k-ε turbulent model with the enhanced wall treatment was adopted to consider the turbulent effect. The numerical results agree well with the experimental data. Two types of heat transfer deterioration were observed in this paper. The first type of deterioration occurs at the place where the wall temperature exceeds the pseudo-critical temperature, while the second type occurs when the bulk fluid temperature exceeds the pseudo-critical temperature. The effects of several key parameters, such as mass flow rate, heat flux, pressure and inlet temperature on heat transfer deterioration were studied in detail. The results reveal that the heat transfer coefficient increases with increasing mass flow rate and inlet temperature. The effect of heat flux on heat transfer is complicated, while the effect of pressure on heat transfer is insignificant. Heat transfer deterioration can be effectively eliminated by increasing mass flow rate and pressure and decreasing heat flux and inlet temperature. The dramatic variation of thermo-physical properties is the main reason for the heat transfer deterioration.

“…The JP-8 is composed of approximately 60% of isoand n-paraffins, about 20% mono-, di-, and tri-cycloparaffins, and aromatics [15]. However, RP-3 aviation kerosene is widely used for civil aviation in China [20][21][22], yet almost no research is available on the feasibility and the performance of neat RP-3 aviation kerosene in CI engines. RP-3 kerosene consists of saturated hydrocarbons (92.1% volume) and aromatic hydrocarbons (7.9% volume), which is different with JP-8.…”
