... thinner than the mean film thickness. Waves were observed on the substrate. Waves of a certain amplitude were confirmed to exist, even on the silicone films near the flooding occurrence, where the film Reynolds number was quite low. The mean film thicknesses of the silicone films, as well...

... of the wall topography for the heat transfer intensification is comprised of minigrooves aligned along the main flow direction. The wall topography affects the development of wavy patterns on the liquid-gas interface. Linear stability analysis of the falling film flow based on the long-wave theory predicts...

... are interpreted in order to describe the mechanism associated with heat transfer augmentation. Heat flux distributions locate the most active areas in heat transfer and reveal the effects of convective mixing. Slanted traveling waves of high temperature are identified; peak values of Nusselt number are attained...

... Method,” J. Mech. Eng. Sci., IMechE Part C, 218, pp. 195–205 ). The work models saturated pool boiling of water at 1 bar on a large (much larger than the minimum wavelength of 2D Taylor waves) and thin horizontal copper strip. The pool height is 0.7 mm , indicating thin film boiling. In the present model...

...Jixiang Yin; Guojun Li; Zhenping Feng This paper reported three-dimensional numerical simulations of the steady laminar flow and heat transfer in corrugated-undulated channels with sinusoidal waves, aiming to investigate the effects of intersection angles ( θ ) between corrugated and undulated...
