A film model for free convection over a vertical porous plate with blowing or suction [PDF]
, 1993 A film model is described for free convective heat transfer and friction in the presence of wall suction or injection. The analysis yields a thermal correction factor, which appears to be the classical (Ackermann) expression, and a novel friction ...

Friction anisotropy at Ni(100)/(100) interfaces: Molecular dynamics studies [PDF]
, 2002 The friction of surfaces moving relative to each other must derive from the atomic interaction at interfaces. However, recent experiments bring into question the fundamental understanding of this phenomenon.

Experimental Investigation of the Thermofluid Characteristics of Shell-and-Plate Heat Exchangers
Energies, 2020 An experimental study regarding the thermofluid characteristics of a shell-and-plate heat exchanger with different chevron angles (45°/45°, 45°/65°, and 65°/65°) with a plate diameter of 440 mm was carried out. Water was used as the working fluid on both

Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
, 2013 The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).
