엔진 온도 평가와 열정산을 위한 통합 열전달 해석 기술 = Conjugate Heat Transfer Analysis to Evaluate Engine Temperature Distribution and Thermal Balance

다국어 초록 (Multilingual Abstract)

The increase of power density is limited by engine temperature. Engine component temperatures are an important consideration. because it will affect material strength and lubricating performance, therefore, it is of great importance tor engine designers to estimate component temperature in the early stage of engine development. In the present work, the conjugate heat transfer analysis of calculating heat transfer between head/block solid components and coolants was used. to estimate solid component temperature distribution and heat rejection to coolant. In particular. unsteady heat transfer simulation method of Intake/exhaust valve system were developed. The calculation results were presented and compared with experimental results to confirm the validity of this methodology. It is also applied to optimize engine cooling system through thermal balance.
