摘要：Take the rotating detonation engine combustion chamber wall which under great heat flux as the research background. The characteristics of impingement cooling under different parameters were studied by numerical simulation, then analyzing and getting a better Impingement cooling structure. It is found that under the same air mass flow rate and constant heat flux, when the diameter of impingement hole is d=4mm, the impingement distance is H=4mm, the hole spacing is Xn=Yn= 35.168mm, the cooling effect is the best. With the cooling structure, the cooling of the heated wall with constant heat flux of 500000 W/m(2) was studied. The results show that when the Reynolds number is Re = 50000, the wall is cooled and the wall temperature is reduced to a reasonable range.
