热声发动机的优化计算设计
Optimization Analysis of A Thermoacoustic Engine
  
中文摘要:
      把改进的12-Bit格子气模型用于复杂边界的热声发动机的模拟研究,成功模拟了带共振腔的驻波管中热声振荡演化过程。对热声板叠的长度、热声板叠在共振管中的位置以及共振腔的几何大小对热声振荡振幅的影响进行了数值计算。计算结果显示,当共振腔与细管的宽度比为2.2,板叠位置相对于细管长为0.34时,驻波管中热声振荡振幅达到最大。共振腔尺寸的研究,对于热声发动机性能的的优化设计有指导意义。
英文摘要:
      A improved 12-bit lattice gas method was used to simulate a thermoacoustic engine with complicated boundaries.The evolution process of self-excited thermoacoustic oscillation in a standing wave tube with a resonator was simulated successfully.The optimization of the length and position of a regenerator as well as the size of the resonator were studied numerically.The results show that the sound oscillation reaches a maximum when the size ratio of resonator and the tube is 2.2,and the position of regenerator relative to the length of the tube is 0.34.A study on the size of a resonator is valuable to the design of a thermoacoustic engine.
