Using a Heat Phase Adjuster to Modify the Heat Flow in a LoopTube Type Thermoacoustic System

Abstract

It is suggested a technique to increase the thermoacoustic system's loop-tube type energy conversion efficiency.
A heat phase adjuster's (HPA) local thermal input introduces acoustic boundary conditions. The sound intensity
was raised in the prior investigation by using HPA to adjust the sound field. This work focuses on the
modification of heat flow in the stack utilizing HPA to clarify the process for increasing efficiency. While
varying the thermal input to HPA, the experiment measures the sound pressure inside the tube and the stack's
temperature. Using the transfer matrix approach based on the Rott equation and taking the temperature gradient
into consideration, the sound fields inside the tube are assessed. The rising levels of HPA in a variety of
circumstances
