Heat Conduction Analysis of the Cylinder Head in Turbocharged Gasoline Engine by Boundary Element Method

경계요소법에 의한 터보과급 가솔린기관 실린더헤드에 대한 열전도 해석

  • Published : 1989.07.01

Abstract

The temperature distribution and heat flux of the inner wall of the cylinder of turbocharged gasoline engine were calculated by the 3-dimensional heat conduction analysis employing boundary element method. Overall mean effective heat transfer coefficient and thermal resistance ratio and equivalent thickness of the cylinder wall were calculated. the numerical results were discussed with respect to the engine speed, equivalence ratio, spark and boost pressure.

본 해석의 목적은 실린더헤드의 3차원 열전도해석을 격자망구성이 편리한 경계요소법을 이용하여 수행함으로써 연소실의 벽면온도를 구하여 연소 실내의 열전달과정 해석을 위한 사이클 시뮬레이션에 사용하는데 있다.
