Reverse osmosis is a widely employed technology for the desalination of highly mineralized mine water. However, achieving zero liquid discharge (ZLD) through subsequent evaporation and crystallization resultant concentrated brine incurs significant costs energy consumption. Solar interfacial water presents promising alternative generating fresh from both seawater wastewater. Nevertheless, under high-salinity conditions, formation salt crystals on surface evaporators hinders light absorption, thus diminishing efficiency. This study introduces three-dimensional (3D) columnar sponge evaporator synthesized by crosslinking sodium carboxymethylcellulose (CMC) with polyacrylic acid (PAA) incorporating coal-based carbon (MC) materials to develop photothermal sponges (CMC10/x-MC) treatment saline The polymer was formed an esterification reaction between PAA CMC high-temperature pore size tailored adjusting dosage. engineered 3D porous structure facilitated enhanced scattering within its pores, thereby boosting absorption conversion efficiency incorporated carbon. CMC10/x-MC-based achieved rate up 3.72 kg·m-2·h-1 in brines, demonstrating superior performance. Collectively, based CMC10/x-MC solar-driven solution wastewater offers viable pathway addressing challenges associated ZLD processes.

Cooling channels are typically integrated into high temperature flow regulating valves to mitigate the adverse effects of elevated temperatures on operation digital and embedded sensors. However, conventional straight cooling often suffer from inefficient heat dissipation excessive pressure losses. In this study, a novel valve incorporating 12 Tesla is proposed simultaneously optimize transfer enhancement resistance reduction. Three-dimensional steady-state numerical simulations, based Navier–Stokes equations (Laminar model), were conducted analyze pressure, temperature, Colburn factor (j), friction (f). The (j) was determined relationship between absorption, surface difference, area, mass velocity fluid, while (f) derived correlation inlet-outlet hydraulic diameter, fluid. Numerical results reveal that mixed capacity structure improves with increasing inlet pressure. Among schemes, Scheme 1 exhibited highest maximum 0.173, 5 demonstrated best performance lowest 1.357. Experimental validation confirmed close agreement experimental data results, discrepancies within 8.83% for j 6.39% f. Through analysis JF impactor factor, which evaluates combined flow, 11 achieved optimal overall performance, enhancing by up 28.7% reducing losses 17.9%. This study provides valuable insight design valve, their thermal management operational efficiency.
