Kajian Numerik Pengaruh Jari-Jari Stack terhadap Pemanasan Suhu Rendah Mesin Termoakustik Gelombang Berjalan

Abstract

Thermoacoustic is one of the technological sciences that utilizes thermodynamics and waves. The thermoacoustic device is divided into two, namely the thermoacoustic engine that converts heat energy into acoustic waves, and the heat pump used to pump heat from low temperature reservoirs to higher temperatures by utilizing acoustic waves. This study examines numerically the effect of stack radius on efficiency and the value of low heating temperature of thermoacoustic engine. The result that the low heating temperature is 124  at radius 0.12 mm.
