“…Due to the high total temperature of free stream, air cannot be used as the coolant anymore as in the traditional engines. Regenerative cooling using endothermic hydrocarbon fuel has been considered as the most promising cooling method for the scramjet [4,5,7,8]. Fuel flows through the wall to cool it down before it's injected into the combustor.…”

Hydrocarbon fuel has been widely used in airbreathing scramjets and liquid rocket engines as coolant and propellant. However, possible heat transfer deterioration and threats from local high heat flux area in scramjet make heat transfer enhancement essential. In this work, 2-D steady numerical simulation was carried out to study different schemes of heat transfer enhancement based on a partially filled porous media in a tube. Both boundary and central layouts were analyzed and effects of gradient porous media were also compared. The results show that heat transfer in the transcritical area is enhanced at least 3 times with the current configuration compared to the clear tube. Besides, the proper use of gradient porous media also enhances the heat transfer compared to homogenous porous media, which could help to avoid possible overtemperature in the thermal protection.

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
