Effect of Load on Characteristics of Wall Attachment Amplifier

抄録

The purpose of this paper is to clarify the relationship between the flow condition in the wall attachment amplifier and its characteristics. The flow patterns are observed in detail in cases of the flow divided by the splitter and the flow joined with a reversed flow from the output port of the non-attachment side, and the cause of the existence of these flow patterns and its effect on the characteristics of the amplifier are experimentally investigated. The flow models in the amplifier are proposed by referring to the experimental phenomena and the effect of load on the characteristics is theoretically investigated. The theoretical calculation on the characteristics agreed fairly well with the experimental results. It was made clear by the calculation that the flow pattern in the amplifier depends only on the load condition of the attachment side regardless of the load condition of the non-attachment side.
