Temperature Field of a Falling Film with Constant Heat Flux Boundary Conditions and Its Influence on the Infrared Detection Range

  • 摘要: 深入分析了利用恒热流边界条件下下降液膜(降膜)技术对军事目标垂直进行红外抑制的方法。建立了层流降膜的流动与传热模型,采用能量守恒法,忽略液膜入口段效应,得到了降膜表面的温度分布,简化了求解过程。通过与不同研究者结果做对比,验证了能量守恒法对于评估降膜在充分发展段换热过程的有效性。计算了探测器对采用液膜红外抑制技术后目标的识别距离,结果表明:增大液膜流动的流量、合理控制液膜入口温度可增强对特定目标的红外抑制效果。本人的研究方法和结论对军事目标的红外抑制领域具有中重要的参考意义。
