| description | The purpose of the muffler is to reduce the exhaust noise
produced by the engine. The main objective of this study
is to simulate and investigate experimentally the muffler
of the Alfa Romeo 145 vehicle. The dimensions of the
muffler were used to perform the simulation. Experimentations were performed with the same muffler
to develop a relationship between the noise and back
pressure on muffler design. The performance of a muffler
is based on Insertion loss, Transmission loss, and Back
pressure. To study the performance of the muffler,
simulation was carried out using GAMBIT software with
FLUENT. GAMBIT was used to create a mesh surface
and to define the boundary conditions of the required
object, which was read and analyzed by FLUENT. The
experiment on the actual muffler of Alfa Romeo 145 was
conducted at different engine speed. Experimental
investigation was performed on four parameters:
manifold temperature, tail pipe temperature, manifold
pressure and sound pressure level (SPL). Curves are
drawn and analyzed using the measured parameters. |
