ME Dissertation Project:
cylinder block -- finite element study”
SYNOPSIS:
Heat transfer between the working fluid and the combustion chamber in an internal combustion engine is one of the most important parameters for cycle simulation and analysis. The heat transfer influences the in cylinder pressure and temperature levels, engine efficiency and exhaust emissions.
Heat
transfer measurements within internal combustion engines have become
increasingly important with the drive towards higher efficiencies and cleaner
exhaust emissions as well as increased energy levels at the exhaust for
turbo-charging. Although internal combustion engines have been studied for many
years the combustion chamber temperature and heat transfer rates have been
investigated to a lesser extent.
During a
combustion cycle the peak gas temperature can reach levels around 2500 K. The
metal components of the combustion chamber can withstand approximately 600 K
for cast iron and 500 K for aluminum alloys (Lim, 1998). Hence, cooling of the
cylinder head, block and piston is required. The heat flux levels experienced
in a combustion chamber varies both spatially and periodically and reaches levels as high as several MW/m2. Indeed this can
lead to local regions with high thermal stresses resulting in cracking of the
components. Furthermore, lubrication of the cylinder walls is achieved with a
film of oil, which will deteriorate above approximately 450 K.
The objectives of present investigations were:
·
To
determine a suitable heat transfer correlation for the present study by a
comprehensive literature survey.
·
To
create an approximate geometric model of the cylinder block using the solid
modeling software CATIA V5 R14.
·
To
convert the geometric model into corresponding FEM model by meshing the model
using the software Hyper mesh V7.
·
To
carry out a heat transfer analysis under different operating condition of 2
strokes IC engine cylinder block.
A parametric study was carried out by
considering different speeds of the engine. FEM techniques will be used in the
investigation. The front-end commercial software ANSYS 7.0 will be used for the
analysis.
Some
typical results of the investigation:
