A novel method for the determination of frictional resistance coefficient for a plate with inhomogeneous roughness

open access: yesOcean Engineering, 2021
Ship performance is largely influenced by roughness on immersed surfaces, which is mostly inhomogeneous. Therefore, the prediction of the effects of roughness on ship performance is of crucial importance. Even though it has several drawbacks, the Granville similarity law scaling method is widely reported in the literature for predicting the frictional ...

Friction coefficient and wear resistance of a modified polypropylene impregnated with different oils [PDF]

open access: yesIranian Polymer Journal, 2016
The aim of the study was to determine the changes in the sliding friction coefficient and wear mechanism of PP impregnated by oils with respect to the unmodified PP under dry sliding conditions. The study showed that the impregnation of the PP clearly influenced the wear rate of PP and its friction coefficient. During the test, the wear behavior of the
