Numerical simulation of flow and heat transfer performance in turntable

  • 摘要: 针对受燃烧室出口高温燃气冲刷的摆盘装置的冷却水回路,建立二维、三维物理仿真模型,模拟了冷却水在内部流道的 流动与换热过程,考察了冷却水进口压力、冷却水流量对流阻和换热性能的影响.结果表明:①摆盘冷却水进口压力由2.3×105Pa提高到8.3×105Pa,摆盘壁温变化微小,结构1壁温升高5K,结构2壁温升高7K;②冷却水进口速度由0.5m/s提高到5.3m/s,结构1壁温降低约120K,结构2壁温降低约100K,冷却效果明显;③结构2通过缩小流道的流通面积,能在更小的冷却水流量的工况下得到更好的换热效果.
