Internal

Engines
Comprehensive CFD Simulation
of Combustion in
an Old Designed
Engine
This project was
performed in
2002 with the
aim of
optimization of
an old engine.
At the first
step a 3D model
of the
combustion
chamber was
created and a
professional
mesh with the
consideration of
valve and piston
movement was
generated. Using
User Defined
Functions and
Dynamic Mesh
Module of Fluent
Software, 720
degree of crank
angle rotation
was simulated.
Number of Valves
effect on mixing
and combustion
was also
studied. Based
on studies in
this field, a
deep insight
into internal
combustion
engines
simulation and
optimization was
formed in Arya
Alborz Company.

Optimization of
Two Inlet
Manifolds Using CFD Simulations
These two
projects were
performed in
2006 on two old
designed engines
to identify the
potentials of
modification
with the
consideration of
uniform air
distribution and
volumetric
efficiency
increment. Lake
of computer
simulation
facilities in
the past
resulted in poor
design. So in
this project
these two
manifolds were
simulated using
CFD techniques
and geometric
optimizations
with mentioned
targets were
implemented.
