Falling film heat transfer is a process in which a thin film of liquid flows over a surface, typically a horizontal tube, facilitating efficient thermal energy exchange. This phenomenon is critical in ...

When water drains from the bottom of a vertical tube, it is followed by a thin film of liquid that can adopt complex and beautiful shapes. KAUST researchers have now studied exactly how these "fluted ...

Using hollow tubes of varying diameters and high-speed imaging, KAUST researchers captured the hidden shapes of the thin liquid film left behind after water flowed ...
