- Because hot conductibility is extremely low, adiabatic effect is good.
- To predict the slot film-cooing adiabatic effectiveness, a mathematic model was developed based on cohence non-isothermal jet theory.
- The film-cooling adiabatic effectiveness was investigated by the heat-transfer experimental method with different pitch between inlet holes of the slot film.
- Appropriate of air conditioning room spells wooden floor, if spread carpet, the adiabatic effect in the winter will be better, but when choosing carpet, do not use plastic carpet.
- The results show that the influences of different positions of coolant holes, their arrangement and the blowing ratios on the adiabatic effectiveness are obvious and complicated in the leading edge.
