In this paper, we used molecular dynamics (MD) simulations to evaluate pool boiling on nanostructured surfaces containing rectangular, triangular, and cylindrical grooves. Cylindrical grooves exhibited the shortest nucleation time for both single- and double-groove structures, followed by rectangular grooves; triangular grooves performed the worst. Both single- and double-groove designs exhibited superior heat transfer performance compared to smooth surfaces.
