| 摘 要： | 不合理的进气结构造成一次表面回热器(PSR)内部物流分配不均匀,影响同热器内部流体的流动和传热效果.本文提出了具有导流片的进气结构,并在尽可能地保证出口截面速度均匀分布的前提上,开展了不同进气结构对回热器芯体入口物流分配影响的研究.结果表明,在所研究的雷诺数范围内,改进后的进气结构中各通道出口截面速度的最大波动只有14...

| Abstract: | The flowing and heat transfer in the primary surface recuperator(PSR) can be influenced by unreasonable inlet structure which results in uneven material flow distribution.Inlet structure with deflector plate is presented and the impacts of different inlet configuration on the material flow distribution is studied based on the uniform outlet velocities.The results show that outlet velocities fluctuation range are 14% to maximam for improved inlet construction in the range of the discussed Reynolds number,whi... |
