Additionally, to reasonably explain CHF phenomena on micro/nanostructured surfaces, a modified macrolayer dry-out model , the effect of thermal conduction on a heater surface , and capillary wicking  have been presented as key mechanisms. However, these HKI272 are qualitative ideas and a generalized theory has not yet been established.
Although CHF phenomena are extremely complicated and occur in a severe boiling state, secondary compounds may be possible to partially explain their physical nature based on the above researches. Therefore, for the accurate prediction of the CHF value and realizing a further optimized design of a CHF enhancement surface, a comprehensive understanding of previously established researches is required.
