Retaining structure of homogeneous fluid and granular stream is one the main criteria for technological process assuring high quality outcome in many industries, including mechanical engineering oil & gas industry. For example, industry during pipeline transportation oils there a strong trend cluster aggregation, particle coarsening entanglement. Dehomogenization results reverse dynamics stream. The importance prevention minimization small particles coalescence by separating leads to...

The sliding contact when the air together with wear particles flow in area between commutator and brush is considered. dynamical interaction two surfaces probabilistic. behaviour of space-time-varying process described by differential equations, which are generally very difficult to solve. simple numerical solution applying method Galerkin approximation estimate change pressure field thin layer obtained. It was found that under leading edge doesn’t exceed 0.07 maximum value. simulations...

The interaction observed between two surfaces in contact with one another is part of a number physical processes, such as wear. In this paper, we present numerical study the asperities each other. real area varies due to multiple roughness scales caused by stochastic nature asperities. our research, employ tribological system comprising partitions: C1 set (CS), where are direct other, and C2 noncontact set, not Here, have developed new model describe CS using ε-entropy prove existence...

The problems of the dynamic interaction collector elements are covered. It takes into account physical properties material and behavior their parameters features mechanical coupling. A mathematical model dynamics fractions random destruction in contact layer conductivity is created. creates for sliding steady-state.

This paper describes the optical deflector of wave-front corrector a controllable system for compensating random displacements focal image laser beam. The parameters are optimized, and it is tested in detection-and-ranging system. solution produces tenfold reduction variance beam under realistic conditions action turbulent medium.

The problems of the dynamic interaction terminal pair elements are covered. Physical properties material, behavior their characteristics and features mechanical taken into account. Mathematical model dynamics contact layer conductivity fractal destruction for sliding shank sections pairs is created.

One of the most challenging problems is wear articular cartilage caused by surfaces sliding over each other. It could be reduced with benefit synovial layer which have unique lubrication properties. This paper develops model fluid based on Markov theory. In our study, we consider as two-phase solid and liquid phase within joint capsule to frictional characteristics. The formed particle detachment from surface during sliding, lubricant, fluid. We found mean distribution changes in deviation...

The work includes the mechanical analysis of feeders and batchers that find application in various technological processes industrial fields. Feeders are usually classified according to their design features into two groups: conveyor-type non-conveyor feeders. Batchers used batch solid bulk materials. Less frequently, they for liquids. In terms a batching method, divided volumetric weighting batchers. Weighting do not provide sufficient accuracy. Automatic include mass controlling sensor...

Features analysis of propagation for harmonic probing signal having spiral topology ax symmetric conducting inductive structure is conducted. The has violations in the form short circuit adjacent coil’s turns. Visualization results obtained represented involving Parawey fan to spatially display phase distortions during vortex with violation coil topology.
