Solar evaporation is an intricate process coupled across multiple physical fields [1, 2]. Efficient design of solar-driven interfacial evaporators necessitates a thorough understanding of thermal management and water-salt transport dynamics during evaporation [3, 4]. Numerical simulations provide a dynamic and continuous representation of the entire evaporation process, aiding in the comprehension of both macroscopic changes and microscopic details [5]. This enables the optimization and design of evaporators through material modifications and structural improvements. In this section, we highlight recent advancements in using numerical simulations and modeling techniques for solar-driven interfacial evaporation.
