论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。 Choosing one marine controllable intake swirl diesel as the research object,this paper does some calculation and analysis on the intake flow field by using a three-dimensional flow field analysis software,then,obtains the swirl ratio and the flow coefficient of the target diesel in different valve lifts and intake baffle angles , and finds that the intake swirl of the diesel has a two-stage characteristics,namely the value of the swirl changes from high to low.On basis of the calculation and analysis of the diesel air intake system flow field,this article completes the structure optimization design of the diesel intake,and gets the laws of the swirl ratio and the flow coefficient influenced by the structure of the diesel intake.At the same time,this paper verifies the calculating results through using the steady flow test of the diesel air intake system,and ensures the accuracy and reliability of the diesel air intake system calculating analysis and design optimization.
