The effect of bi-modal excitation on the spreading rate of a circular jet
Abstract
The effect of bi-modal excitation at fundamental and subharmonic frequencies is analyzed for the case of axisymmetric shear layer. The interaction between the two forced components were found to be dependent on the phase-difference between them. The growth rate is governed by the production of the turbulence as well as the productions of the two excitation components. The growth rate is dependent on the phase-difference between the two excitation components and is maximum when the subharmonic suffers maximum amplification.
