유한 요소법을 이용한 직접분사식 디젤엔진 실린더 헤드의 온도 및 열응력분포 해석(Ⅰ) = Finite Element Analysis of Temperature and Thermal Stress Distribution of a DI Diesel Engine Cylinder Head(Ⅰ)

다국어 초록 (Multilingual Abstract)

In this study, three dimensional finite element model of a diesel engine cylinder head was made to accomplish heat transfer analysis and also thermal stress and deformation analysis. Heat release analysis and Nusselt-Reynolds relations were applied to determine the convective boundary conditions which is required for heat transfer analysis to calculate temperature distribution. Thermal stress distribution was also investigated in via of heat transfer analysis results. Steady state temperatures and heat fluxes were measured using K-type thermocouples and compared with numerical results to give a guarantee for the plausibility of numerical analyses.<br/>
