Electrospinning Machine | Effects of Microchannel/Macrochannel Configurations on the Evaporation Performance of Internal Vertical/External Radial Hydrogel Solar Evaporators: Experiments and Simulations Insights 2025-10-23
Compared to evaporators with a single structure, hydrogel evaporators with aligned/radial hybrid channels have been proven to synergistically utilize the rapid water transport of aligned channels and the strong thermal confinement capability of radial channels, achieving exceptional evaporation performance (Small 2025, 21, 2411780). However, in the aforementioned composite structures, the size of their aligned structure is not adjustable, and the potential mechanism of how the sizes of micro- and macro-scale channels simultaneously affect water transport and heat transfer, thereby controlling the balance between water supply and heat loss, is not fully understood.
