(a) Schematic of the channel geometry considered consisting of two surfaces with different temperatures. (b) Variation of the height H at constant L and B. (c) Variation of the ratchet baseline B at constant H and L. (d) Variation of the periodicity L at constant H and B. Tableaus (a–c) are drawn to scale with the variations used in this work.
