In seeking for a steady solution of Liouville's equation, the boundary condition is taken into account by requiring that the solution should lead to a given distribution of average density. The distribution is to be determined by macroscopic law of diffusion and ...

WebMar 21, 2024 · The steady diffusion flamelet is more applicable to non-premixed combustion and FGM better for premixed cases. The partially premixed model combines both premixed and non-premixed models and gives you a lot of flexibility, but this does not mean that it is forgiving of poor decisions. WebStable Diffusion is a deep learning, text-to-image model released in 2024. It is primarily used to generate detailed images conditioned on text descriptions, though it can also be applied to other tasks such as inpainting, outpainting, and generating image-to-image translations guided by a text prompt. It was developed by the start-up Stability AI in collaboration with …
