Boiling in helical coils is involved in many applications including nuclear and conventional boilers, air conditioning and refrigeration, and chemical processing. It is therefore important to be able to predict CHF accurately. Many experimental studies have been done and many correlations have been proposed. However, there has been no comprehensive comparison of correlations with data to determine their accuracy. The present study was done to fulfil this need. A database of published test data from 16 sources was prepared and compared to a number of correlations for straight tubes as well as those for coils. The data included six fluids (water, nitrogen, refrigerants), mass flux 89 to 5474 kg m⁻² s⁻¹, and critical qualities from −0.5 to 1.16. Tube diameters range from 4.5 to 20 mm and ratio of coil diameter to tube diameter (D_c/D_t) from 6.5 to 108. None of the correlations for coils was found satisfactory. Four of the five straight tube correlations gave fairly good agreement. Ranges of parameters have been identified in which the straight tube correlations can be used for design.

螺旋线圈的沸腾涉及许多应用，包括核能和常规锅炉，空调和制冷以及化学处理。因此，重要的是能够准确预测CHF。已经进行了许多实验研究并提出了许多相关性。但是，还没有将相关性与数据进行全面比较以确定其准确性。完成本研究是为了满足这一需求。准备了一个来自16个来源的已发布测试数据的数据库，并将其与直管以及线圈的相关性进行了比较。数据包括六种流体（水，氮气，制冷剂），质量通量为89至5474 kg m ^-2  s ^-1，以及-0.5至1.16的临界质量。管直径范围为4.5至20 mm，盘管直径与管直径之比（D _c / D _t）为6.5至108。发现盘管的相关性均不令人满意。五个直管相关中的四个具有相当好的一致性。已经确定了参数范围，在其中可以将直管相关性用于设计。
