Abstract

Simulation studies were conducted on double injector combustion with GO2/GCH4 as the propellant. The effects of different injector spacing on the combustion flow field were compared and calculated using k-ε turbulence models. The results show that the larger injector spacing will increase the thermal load on the front wall of the combustion chamber, but when the injector is close to the wall, the injection fuel will form a protective layer on the front wall and reduce the heat load on the front wall. And the smaller injector spacing facilitates the forward movement of the reaction zone near the axis; Under the condition of small injector spacing, the wall temperature of the rear section of the combustion chamber is higher; A specific inner diameter of the injector has a certain optimal value.
