Analysis of hot heat exchangers performance of thermoacoustic energy converter

Abstract

Thermoacoustic heat engine (TAE) has a component that namely stacks, hot heat exchanger, cold heat exchanger and resonator. The hot heat exchanger is the device that used to supply the heat on the stack to generate an acoustic work. Nowadays, the technology in development of TAE still in progress development, then to be investigated in order to step-up better prediction on the performance and design of TAE. The lacking is the main issue in research of heat exchanger, and as a consequence hot heat exchanger in TAE, the heat exchanger does not have an established method of design. Thus, this report was developed in order to design and analyse on performance test of hot heat exchangers and TAE. In the designed of the hot heat exchanger, the material kanthal was selected as a heating element and it produces the heat input of 490°C as temperature to the system which this value can generate an acoustic work in the system. Experimental studied, the result obtains the power to generate the system is 90watt which the TAE start working after 3 minutes the system was run. The hot heat exchanger supply the heat in the system at range 390 ≤ T°C ≤ 560.
