本文阐述热水锅炉水动力模化试验方法,以及原型与模型相似所必须遵守的条件。提出按照相似理论设计模化试验装置时,可利用流体进入自模化后,流体流动状态及速度分布与Re无关这一特点来简化相似条件。同时以120×10~4kcal/h(503×10~4J/h)自然循环热水锅炉为例,具体说明模化试验装置的设计 This article describes the hydrothermal boiler hydrodynamic model test methods, and prototype and model similar to the conditions must be observed. Proposed according to the similar theory design mold test device, you can use the fluid into the mold, the fluid flow and velocity distribution has nothing to do with Re to simplify the similar conditions. At the same time to 120 × 10 ~ 4kcal / h (503 × 10 ~ 4J / h) natural circulation of hot water boiler, for example, specify the design of modular test equipment
