Seminar Report Abstract: 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 characterized by the following two categories. First, the oscillations induced by temperature differences across a stack of plates can generate acoustic power consisting 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 learned 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 seminar report will show the way for initial and continuing research into thermoacoustics, particularly in the experimental and numerical fields.
Seminar Report on Thermoacoustic Heat Engine for Mechanical Engineering
Thermoacoustics, the latest technology in fluid power has been introduced in the Thermoacoustic Heat Engine Seminar Report. Qualitative and quantitative diagnostic parameters which are important in the thermoacoustic analysis have been discussed with a few example calculations. Application of the solid-fluid interactions in a heat engine is an attractive alternative to the current conventional system based on its simplicity (few moving parts), reliability (no critical dimensions), and environmentally friendly mode, especially for refrigeration application (no chlorofluorocarbons). Studies have shown that it is a technology to be reckoned with, even with its current low performance.
However, as is with all new technologies, more studies need to be done, analytically, experimentally, and numerically, to further and better our understanding of the phenomena in order to realize its full potential in our society. In particular, the potential for use in certain niche applications needs to be addressed.
