경계 요소법과 평면파 이론을 이용한 흡기계 해석

The application of the 4-pole parameter method with 1-D theory is acceptable for intake system analysis. However, the limitaion appears during the analysis of complicated intake system since this method is developed based on the plane wave thoery. For the intake system analysis, the usage of BEM(Boundary Element Method) is introduced describing its disadvantage. To combine benefits of both method, a hybrid method is introduced. This hybrid method consists of the 4-pole parameter with 1-D theory and BEM. The developed method is applied to an automobile intake system analysis to obtain the transmission loss.
