Heat Transfer Analysis of a Diesel Engine Head

Abstract

This paper documents the research carried out at the Josef Božek Research Center of Engine and Automotive Engineering dealing with extended numerical stress/deformation analyses of engines parts loaded by heat and mechanical forces. It contains a detailed description of a C/28 series diesel engine head FE model and a discussion of heat transfer analysis tunning and results. The head model consisting of several parts allows a description of contact interaction in both thermal and mechanical analysis.

Optimization of Cooling Channel for Spark Plug Based on Conjugate Heat Transfer Simulation

“…Due to the symmetry plane and adiabatic plane of the model formed by cutting, the boundary conditions are set to be symmetrical and adiabatic. The heat exchange in the combustion chamber of an aero-engine depends on various factors such as combustion and convection, so there is a large change in different strokes of the engine [20], which needs to be determined based on experimental values. In the absence of experimental data, according to the author's calculation, for the same spark plug model, the average temperature of the firing end face of the engine is proportional to the given convection heat transfer coefficient at the firing end.…”
