This experiment has been carried out to examine the combustion characteristics of heterogeneous combustion field by using Impinging injection and Split injection in a closed bomb. The combustion chamber is equipped with pintle type injection nozzles on each of the opposite walls along the length of the bomb. In this study, we call it “Impinging injection” when the injection is performed at same time by two nozzles facing each other and “Split injection” when the injection is performed at different timing from the ignition.
The main conclusions are as follows; 1) The most suitable condition of injection timing exist for improving the maximum burning pressure and total burning time by using Impinging injection. 2) The flame speed can be possible to control by using Impinging injection timing from the ignition. 3) The heat release rate for Split injection is larger than that of standard Impinging injection.
