Numerical simulation of standing wave in an acoustic chamber

Abraham, Arimokwu (2010) Numerical simulation of standing wave in an acoustic chamber. Masters thesis, Universiti Teknologi Malaysia, Faculty of Mechanical Engineering.



Numerical simulation of two-dimensional unsteady compressible Navier- Stokes equations which consists of mass, momentum, and energy conservation equations, and the equation of state is implemented using a commercial CFD code in a standing wave acoustic chamber. The stack is modelled as a two-dimensional thickness. In this study, heat flux across stack surface placed axially in a resonator was investigated. Heat flux distribution was found to peak at the plate edges. It was observed that energy flow from a “source” at the left end to a series of “sink” at the right end of the plate. At near the middle of the stack, there is no appreciable net energy exchange with the working fluid, and energy could be found to almost being transported axially along the direction from the source to the sink.
