Abstract
Heat transfer is one of a number of
indispensable tools in studying of ICEs, due to its
influence on decisive parameters of operation like
temperature and pressure inside the cylinder. It is safe to
say that modeling of the engine heat transfer is among the
most complex problems for engineers. Application of
numerical methods to predict the heat transfer in a
cylinder of reciprocating ICEs is a process of high
importance, which was recognized from the earliest
stages of their development. This is done to examine
performance optimization and design improvement in
order to meet nowadays demands exhibited on the
engines. This present study focuses on a 3-D transient
state temperature distribution analysis on a gasoline
engine model via formulated of models, simulating using
FEM in-built in the COMSOL Multiphysics software 4.3a
to determine the temperature distribution and gradient of
the engine cylinder head model. The number of degrees of
freedom solved for were 32685 in 383 s (12 minutes, 20
seconds) in the mesh optimization. From the result
obtained it was discovered that the heat transfer in the
combustion chamber of the ICE varies with time. Thus, it
took the engine 10 minutes to complete a cycle vis-a-vis
transfer of heat after combustion and that the heat
transfer starts after 30 seconds of combustion. In
addition, the temperature of the cylinder dropped from
1273.2 K to 301 K over a period of 10 minute.
