In article there are fluid flow mathematical models at the UV-sterilizer with concentric pipes installed in modernized water supply system of passenger car allowing to determine the velocity field of the rotational velocity component and assess the degree of attenuation depending on the chamber disinfection geometry, the inlet pressure in the water system, and fluid properties. There are exact solutions of the Navier-Stokes equations for a rotating fluid between fixed cylinder of infinite length and limited fictitious determined rotating lids provided Poiseuille axisymmetric flow. The decision explicitly contains the product of cylindrical Bessel functions and hyperbolic functions.

Despite significant progress in the development of accounting systems, there is almost universal growth accounting losses of electricity and reduce its quality. Along with the introduction of modern energy efficient electrical problem efficiency of electric energy in the stationary energy sector can be achieved through the implementation of active-adaptive technologies for controlling the operation of compensating devices, controlled means of voltage control, switching and power equipment and diagnosis based on digital technology, including automatically maintain a minimum transmission losses when the load. Management of objects offered no traction electricity consumers based on adaptive technology and hardware-software optimization mode parameters in real time.

The possibility of fatigue crack propagation in the region of compression stresses is considered. After each semi-cycle of cyclic loading the stress-strain distribution near the tip of the crack is determined by the finite element method. It is shown that maximum of the tension stresses increases in the region of compression. The obtained results allow to present the possible ways of the above-mentioned fatigue crack propagation.
