Material removal mechanism depends on the material property and machining parameters
during machining process. This paper investigates the brittle removal mechanism of ductile …

The acoustical behavior of an elliptical chamber muffler having an end-inlet and side-outlet
port is analyzed semi-analytically. A uniform piston source is assumed to model the 3-D …

This work formulates the acoustical performance prediction on a single-inlet/double-outlet
cylindrical expansion-chamber muffler. Expressions for the transmission loss (TL) of the …

THE computation of sound propagation in a nonuniform flow is an essential part of
computational aeroacoustics (CAA). This problem, which can be modeled by the linearized …

For multi-chamber silencers with non-uniform cross-sections at axial direction, the coupling
method based on subdomain division technique is proposed. The silencer is divided into …

Numerical computations are commonly used for better understanding the unsteady
