Noise Pollution
Comprehensive
Simulation of
Gas Turbine
Intake for
Optimization
This project was
performed in
2010 with the
aim of pressure
drop and noise
reduction of a
25 MW Hitachi
gas turbine
intake. Poor
aerodynamic
intake design
leaded the flow
separation,
pressure drop
and noise
increment.
Separation
formation in
intake duct can
produce wakes
and turbulence.
Wakes can also
produce a
pressure
pulsation on IGV
and eventually
cause the life
reduction. In
this project at
the first step a
precise 3D model
was created from
the intake duct
of Hitachi gas
turbine. After
precise CFD
simulations the
optimization
potentials were
found out. With
aerodynamic
optimizations,
considerable
pressure drop
and noise
reduction was
achieved. In
this project the
knowledge of
intake and
exhaust
optimization was
produced in Arya
Alborz
engineering
group.

CFD
Simulation of
the Second Stage
of a CNG Gas
Regulator
This project was
performed in
2014 with the
aim of flow
control and
noise reduction
in a gas
regulator.
Because of high
gas velocity,
the accuracy of
machining
process can have
significant
effect on
discharge and
noise pollution.
After a precise
3D modeling and
mesh generation,
detailed
simulation of
flow and
pressure
fluctuations
using LES
turbulence model
was performed.
Based on studies
in this project
a deep insight
into high Mach
number
compressible
flows and
different
strategies for
noise pollution
reduction were
provided in Arya
Alborz Company.
