As the development of electrical equipment， the issues related to wet steam around high-power long-blade are also becoming increasingly prominent. To solve the dehumidification problem in the long blade

this paper draws inspiration from the cell topology of diamond to propose a supporting framework structure suitable for the hollow cavity of dehumidification stator

and designs a biomimetic hollow stator based on this framework. A simulation model is constructed to analyze the distribution of water films on solid surfaces

comparing the surface water film distribution of non-heated stator

ordinary hollow stator

biomimetic stator

and improves biomimetic stator under high-temperature steam at different flow rates. It is found that the biomimetic framework structure can significantly disrupt the flow of heated steam

and through structural design

it can effectively enhance the local heat transfer on the blade surface

achieving targeted dehumidification. When the high-temperature steam introduced has a mainstream mass flow rate of 5%

the surface water film thickness of the biomimetic stator is only 8% of that of the non-heated stator. When the high-temperature steam flow rate is reduced to 3%

the maximum surface water film thickness of the improved biomimetic stator blade decreases by 0.2 μm compared to the basic biomimetic stator

achieving a thickness of 1.05 μm

which is 15% of the non-heated condition. This indicates that the biomimetic framework structure significantly improves the heating and dehumidification efficiency of the long blades.
