| Abstract: | This paper presents the characteristics of turbulence distribution in the swirl combustion chamber of a motored diesel engine tested by LDA. The test system of LDA was summarized. Handling means of experimental data was raised. The law of changes of the turbulence intensity in swirl chamber to the changes of time and space was investigated. The influence of the turbulence features on the mixing of fuel oil air and the combusting was also analyzed. It shows that the air flow is unsteady and the turbulence structure is anisotropic. Its distribution characteristics of turbulence intensity is advantageous to the mixing of fuel oil air and combusting. |
