摘　　要：用化学试剂TiCl4对丝管式冷凝器周围空气的流动进行了可视化研究。实验结果表明,丝管式冷凝器周围空气的流动属于紊流。据此,建立了计算冷凝器周围空气温度的数学模型,采用数值模拟的方法,对稳定状态下冷凝器周围空气的温度进行了仿真,并与实验数据进行了对比,验证了所建立数学模型的正确性。这个新模型对冷凝器的优化设计提高设计精度具有一定的指导价值。A visualization experiment was conducted to determine the flow state of the air around a wire and tube condenser, by using reagent chemical TiCl4. It was found that the flow state was turbulent. Based on the experiment, a mathematic model was established to calculate the air temperature distribution around the wire and tube condenser. Numerical Heat Transfer software was applied to calculate the air temperature field in the stable state. The calculation results were well in agreement with the experimental data. The present new model can be used to optimize the design of a wire and tube condenser.
