Based on the high-temperature air cooling problem faced by the modal connection of aerospace aircraft engines, a precooler scheme using supercritical-pressure methane as the coolant was proposed, and numerical studies on the effects of methane inlet parameters and air inlet parameters on heat transfer performance were conducted. The characteristics of inner-wall temperature and heat transfer coefficient along the precooled channel were analyzed. The comprehensive heat transfer mechanism of precooler was explained through the temperature field, velocity field, and field synergy angle distributions. The turbulent kinetic energy distribution and its impact mechanism on heat transfer were investigated. The heat transfer performance and entransy dissipation of precooler were quantitatively evaluated. The heat transfer prediction of precooled channel was achieved by correcting the Gnielinski formula through density ratio. Numerical results indicated that the high-temperature air was mainly cooled by the channels outside the precooler, and an uneven velocity field on the air side was observed. The appearance of local large vortexes and strong turbulent clusters played a role in improving field synergy and enhancing heat transfer. Methane should be subjected to lower pressure, and the higher air inlet temperature and methane mass flux indicated the better heat transfer performance of precooler. The new correlation formula for heat transfer prediction in the precooled channel was basically within the range of ±18%.
