Flow Friction Behavior in Porous Channels
Fluids Engineering, 2005A series of experimental studies on the flow friction behavior in a rectangular channel filled with various porous metallic foam materials have been performed. The rectangular channel has a cross-sectional area 60mm × 25.4mm with a length of 60mm. The parameters and conditions of interest in the study are the Reynolds number (Re) and medium porosity ...

Modeling of dynamic behaviors of friction
Mechatronics, 2008This paper deals with modeling of dynamic behaviors of friction in the sliding regime. Using a hydraulic cylinder, friction characteristics are experimentally investigated under various conditions of velocity variation. The friction force of the hydraulic cylinder is measured based on the equation of motion using measured values of the pressures in the

Essential Friction: Error-Control in Organizational Behavior
1993In the physical world, interaction without friction is nearly inconceivable. The most elaborate mechanisms would be required to pick up a bottle, set a table, drive a car, or walk to the door. Objects set in motion, whether pencils, mice, feet, automobiles, or trains, would slide freely until arrested or deflected by collision with another object ...

Friction and Wear Behavior of Cobalt
Journal of Lubrication Technology, 1975An investigation has been made of the friction and wear behavior of polycrystalline cobalt, over a wide range of rubbing conditions, to establish the general pattern of wear. Evidence has been obtained for the occurrence of three transitions, namely, mild to severe wear at low loads and speeds, severe wear back to mild at higher loads and speeds and a ...

Frictional behavior of the correlated chain
Die Makromolekulare Chemie, 1972AbstractThe friction coefficient of linear macromolecules is calculated for the correlated chain model using KIRKWOOD's approximation. This model (proposed by SANCHEZ and FRANKENBERG) incorporates a certain long‐range correlation between the segments of a random chain, and contains two parameters: CF, which depends on this correlation (CF = 1 for a ...

Elastohydrodynamic Friction Behavior of Polyalphaolefin Blends
1998Many practical lubricants are produced using mixtures of different base fluids. It would clearly be of value to be able to predict the likely EHD friction properties of such blends from the measured properties of their individual components. The initial stages of such a study were aimed at establishing and understanding appropriate test methods and ...
