Kertas kerja ini memperkenalkan teknologi terbaru dalam kuasa bendalir iaitu termoakustik, fenomenon yang disebabkan oleh interaksi pepejal-bendalir. Secara umumnya, termoakustik boleh dibahagi kepada dua kategori. Kategori pertama ialah enjin haba, di mana kuasa akustik dapat dijana hasil daripada gelombang yang wujud disebabkan oleh perbezaan suhu yang merentas suatu susunan plat. Keadaan sebaliknya untuk pam haba, di mana pemindahan haba berlaku merentas suatu susunan plat dengan kuasa akustik masukan dalam bentuk gelombang akustik. Teori asas termoakustik dan beberapa parameter reka bentuk sistem termoakustik yang diguna penyelidik masa kini dibincangkan disini. Analisis dengan menggunakan teori tersebut juga dilakukan. Perbincangan ini adalah sebagai dorongan untuk penyelidikan dalam bidang termoakustik khususnya secara eksperimen dan analisis berangka.
Kata kunci: Termoakustik, parameter reka bentuk, analisis
This paper is an attempt at introducing the latest technology in fluid power, thermoacoustics, a phenomenon due to solid-fluid interactions. Thermoacoustics can be generally characterised by the following two categories. The first, the oscillations induced by temperature difference across a stack of plates can generate acoustic power consistent of a prime mover. While the reverse, that of heat transfers across a stack of plates powered by acoustic waves is typical of a heat pump learnt in the engineering introductory course. Basic thermoacoustic theory and some simple thermoacoustic design parameters that are currently being used are discussed. Analysis using these theories is shown. Discussions through this paper will show the way for initial and continuing research into thermoacoustics, particularly in the experimental and numerical fields.
Key words: Thermoacoustics, design parameters, analysis
