Mechatronical System of Testing of Hydrodinamical Bearings
Solid State Phenomena, 2006This article presents a Mechatronic Hydrodynamic Bearings Testing System and describes its main functions. The System’s structure, control and principles of data input/output are given here. The System enables one to evaluate the quality of bearings by spectral analysis of oscillations and orbits of the rotor pivot.

A hydrodinamic effect that can be used in small discharge measurement
Flow Measurement and Instrumentation, 2003Abstract If a heavier than water body is introduced into a tube filled with water, closed at one end, and if the tube is turned over 180°, the body, surprisingly, will go upward and the water will flow downward. For this presented fact, a theoretical model was developed by using the momentum equation.

KINEMATICS OF MULTI-STAGE MATCHING GEARBOXES FOR HYDRODINAMIC TORQUE CONVERTERS
World of transport and technological machines, 2021The study offers a design solution for online capacity adjustment of hydrodynamic torque converter powertrains. It is proposed to install a step-less speed drive or multistage matching gearbox between the engine and the torque converter to adjust the powertrain properties on the move depending on the current operating conditions.

Hydrodinamics of liquid film on cylindrical surface
2017A theoretical study of the film movement of the liquid phase on the surface of a permeable cylinder under the influence of the mass forces of gravity and the swirling gas flow has been carried out. The differential equations of motion were determined for the first time, the exact solutions for the velocity components provided adhesion film on the ...

Hydrodinamics in the swash zone
2000This paper describes a study of the hydrodynamics in the swash zone using an impermeable concrete beach in a laboratory flume. Analysis was made of the measurements achieved using level wave gauges and a laser Doppler velocimeter. From these measurements we could derive the mean motion and turbulence characteristics along the main flow direction in ...

Particular analytical solutions of the hydrodinamic equations
1987Some particular solutions of the hydrodynamic equations are presented. In the solutions the velocity is a complex exponential on space variables, i.e. it is a real exponential multiplied by sine and cosine functions. The amplitude of the exponential is a time dependent complex vector.

[Features of hydrodinamics in drainage of the upper urinary tract (experimental study)].
Urologiia (Moscow, Russia : 1999), 2013The present article is devoted to the search for the physical factors affecting the intrapelvic pressure in patients with kidney catheters. Based on mathematical prediction and experiment, value of air bubbles, hampering urine outflow and contributing to the development of purulent postoperative complications in urology, was demonstrated.
