Maxwell-Stefan Diffusion
Maxwell-Stefan diffusion describes how different chemical species move through a mixture by considering their mutual interactions, rather than just concentration differences. Instead of diffusion being driven solely by a concentration gradient, this approach accounts for the friction and resistance that molecules exert on each other as they diffuse. It provides a detailed understanding of how species influence each other's movement, especially in complex mixtures or under conditions where interactions are significant. This model is useful in fields like chemical engineering and materials science to predict and control the transport of multiple components in gases and liquids.
