Simulation of Change in Density and Viscosity of Crude Oil When Mixing

The deviation of density and viscosity values of oil mixtures from those calculated according to the additivity rule has been examined. Mathematical models have been developed for determining the properties of mixtures with different compositions taking into account the group composition of the source components. Mixtures containing components with a high content of alkanes and a low content of arenes have been found to be characterized by extreme deviations of density towards the maximum and kinematic viscosity towards the minimum.

STUDY OF FLUIDITY AND KINEMATIC VISCOSITY OF ORGANIC SILICONAL LIQUIDS AND MIXTURES BASED ON THEM

Preliminary studies have shown that hydrophobic materials ZDP "Silicon Polymer" 136-157 M, ETS-32, ETS-40, and a number of their analogs, in contrast to GKZh-11N and GKZh-11K, can withstand excess water pressure of 0.02 MPa when tested for methods developed based on standard methods for determining the water-resistance of concrete and tiles. The authors of the article developed experimental waterproofing liquids 1 K, 2 K, 1 N, and 2 N, based on GKZh-11 N and GKZh-11K. These liquids are ready for use for hydrophobization and silicatization of organosilicon compounds.

Investigation of the effective parameters of scuffing failure in gears

This study investigates the effective parameters of scuffing failure in gears using the integral temperature method. For this aim, the mass temperature, integral temperature and scuffing safety factor are calculated for a given parameters. Then, integral temperatures are simulated based on various geometrical, operational and lubrication parameters. Obtained results are presented graphically. The obtained results show that increasing the module mn results in a decrease in the integral temperature ϑint.
