Web8 de abr. de 2024 · In conclusion, grooves can delay Gortler vortex-induced transition by modifying the Gortler streaks structure and instability, which would shed light on hypersonic boundary layer transition control. WebIt is speculated that the atmosphere of Venus up to around 4 billion years ago was more like that of the Earth with liquid water on the surface. A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases. [7] [8]
