Hypersonic vehicles with turbojet, ramjet, and scramjet engines are expected to be widely
applied to future transportation systems. Due to high-speed flight in the atmosphere, body …

Supercritical fluids (eg, hydrocarbon fuels, water, carbon dioxide, and organic working
medium, etc) have been recognized as working media to improve thermal efficiencies in …

Regenerative cooling technology is widely used in the active thermal protection system of
hypersonic airbreathing engine. However, the overall efficiency of active cooling with limited …

The supercritical CO 2 closed-Brayton-cycle (CBC) is a highly promising integrated scheme
for cooling and power generation in hypersonic vehicles. However, the CO 2-fuel printed …

Regenerative cooling plays a critical role in the thermal management for scramjet
combustors, and the design of cooling channels is of utmost importance. To …

Gravity and/or flight acceleration would lead to significant buoyancy effect on heat transfer of
a hydrocarbon fuel in the propulsion system. Large eddy simulations have been conducted …

The cooling capacity of regenerative cooling channels is still insufficient for the liquid rocket
engine due to the high temperature of the combustion chamber and the little refrigerant …

In order to improve the active regenerative cooling performance of a scramjet using
supercritical n-decane, a new type of cooling channel, the double-layer channel, is …

This study presents a brief review on the buoyancy criteria for supercritical fluids (mainly
water, carbon dioxide and hydrocarbon fuels). Buoyancy affected heat transfer at …
