Abstract

The JMC actuators need a monopole and a dipole radiator. The planar monopole and dipole source types and their source strengths, especially to be applied to the JMC method, are defined with the uniform flow present. They depend on the Mach number of the flow. JMC based unidirectional two-element source configuration in a duct is introduced in the case of uni-form axial flow. The elements produce both the monopole and dipole parts of radiation. The solution can be realized with no inter-channel delays, even in the case of flow, which is advantageous in the practical implementation of digital control systems.
