摘要
传统的热机按一定的热力学循环要求 ,用热机的机械结构和运动规律组织工作介质的状态变化 ,实现热能与机械能之间的转变。热声热机则是运用热声原理在一定的几何和热力环境条件下 ,利用系统与工质自身性质及各个部分之间进行的一种热力学自组织过程实现热能与机械能之间的自主转化。实践中可以实现无运动部件的热机系统。
According to thermodynamic cycle, conventional thermal machinery completes conversions between thermal energy and mechanical energy, which are controlled by mechanical structure of thermal machinery. However, basing on thermoacoustic effects, thermoacoustic thermal machinery completes the same functions as conventional thermal engine automatically under certain geometry sizes and thermal environments, which should match with working materials in the system to satisfy the principle of thermodynamic self organization. The advantage of thermoacoustic thermal machinery is that it can be made as machiery without any moving part.
